I've been home from college just finished my freshman year and I've been literally hungry the entire summer. Every penny I have I have to save for school because my parents can't afford to help me. Long story short I work from home I don't have a car and I live in the country we have no public transportation and I couldn't work anywhere walking distance.. It's not like I have hundreds of dollars a month to dump on food.. So I figured I'd just starve these four months until I go back to school. Now I'm feeling sick.. I'm light headed, weak, I have horrible tingling in my hands. When I'm really hungry I just go to sleep. My mom acts like it's ok for everyone in the house to not eat. We get food stamps but she didn't get food this month??? So I have no idea what happened but I'm not going to ask questions.. We had a lot of bills that were close to cut off. She will go to bed and not eat half the time and that's not good for her either. If I ever had anyone over they would think I was crazy downing 8-10 cups of water and not eating a single thing.

When we do get food stamps My brother lives with my dad but during the summer he will come here and eat for two weeks then me my mom and grandma have to starve until the end of the month.. It's just not enough... What can I do?

We scrape almost anything up for dinner every night I'm doing hip hop abs in the morning and elliptical for 30 mins in the evening which is really intense. I find myself in a bad mood, weak and hungry. I don't know what to do. I can barely eat once a day. Should I try to find tablets to deal with hunger or meal replacement shake? I only have $10 credit on my Amazon.

I'm 19, I'm in college studying to be a Psychiatrist. I make good greats, have accomplished many academic achievements in school, also trying to get involved in my college. The "model child" but none of that matters to me at all because I am so lonely and I feel like I have no hope for the future. Every day I'm depressed... For the pass 3 days I've felt like a complete vegetable..

I feel ugly, no matter how hard I try I know a better option exist out there. I see couples on social media and want to cry. I see people taking trips and enjoying life and I'm stuck struggling and unhappy.

I'm almost 20 and that's so scary to me I feel like I've never lived my life.

I am 18 and I have never been in a relationship and Im really lonely. However, Im not in a rush to be in one either. But how do I overcome such loneliness? I honestly feel like I've never really had the high school experience I had a lot of people I'd chat with during classes and stuff but I never had a true friend no one texted me outside of school or wanted to make plans. So I wouldn't say I was a "loser" because I talked to so many people everyday I was probably in the middle on the popular scale but it seemed like I never actually did stuff. I never partied, smoke or drank and now Im feeling a little scared of college because I never did any of this stuff and I don't want to end up "that girl" in college. Any advice?

Im very close to having absolutely no food at home. My mom shouldve went shopping almost a month ago. Im losing weight, Im constantly dizzy or laying in bed trying to go to sleep to avoid hunger pains. My brother is 16 and I know he probably feels twice as hungry as I am. We are sooooo low on food and if I do fix something I can only have a little so everyone else gets a chance to eat... Im tired of crying from hunger and looking at food online. Everyday I wonder what Im going to eat tmrw. is there anything I can do? Anyone I can call? Im so hungry..I just pray I pass out so I can be taken to the hospital and fed..

Any ideas?

lately it seems like whenever im in my bedroom (kind of a depressed place to be in) or if im upset or worked up about something i immediately get this chest pain, my lungs feel like a tight balloon i cant take a deep breathe and my eyes get really watery and i get the sensation of wanting to cry..(but i dont) i tear up a little. my face will overall look a little red. but i dont feel like im dying which most people say its not severe enough for me to run and call 911 but the chest pain and breathing is pretty moderate. it can last up to an hour..

Im not starving but I know me and my brother arent eating enough I try to eat at least once a day but I dont want to be greedy because then I feel like Im not allowing everyone else to eat... theres 4 people at my house and sometimes I feel like theres not even enough food for one person. The worst part is I do Insanity workouts 6 days a week so whatever I eat I burn so after my workouts Im extremely weak and shaky everyday.All I do is lay in bed all day because Im so weak and Im tired of being hungry I look at food online and dream of Mcdonalds and buffees.... my mom said she was broke on pay day which was 2 weeks ago and we needed food then I dont know if I can do this another day...

Ive always felt like Ive been a sensitive person who gets hurt easily but I would say January I started having all these feelings that were completely out of control... nothing triggered it i just felt literally numb to the world i cant get out of bed and when i wake up this guilty n scared feeling just hit me like wtf im not trying to wake up feeling sad but it just happens it was to the point id just lay in bed all day n when my mom came in saying i had to get up n eat i would just look at my plate n cry. I cant take these constant unwanted thoughts

So I took my driving test for the second time I parallel parked perfectly, drove perfectly. Pulled in back at DMV and the lady looked at me and said she couldnt pass me. She didnt feel like I was ready. Honestly, I could drive across the globe safely Ive been driving on my permit for about threee years. Today my permit expires now I have to start over and take the written test. :/ i cant get this off my mind i dont want to drive anymore.

I am so hungry. I was pretty healthy until Christmas break now when I wake up I'm extremely weak and shaky. My mom and grandma allowed my grandmothers boyfriends son stay here in the basement while he is working. Sometimes he gives $40-50 but thats never enough considering he makes $400 every week. And he blows the rest on video games and he is suppose to save up so he can leave. He will take an entire bag of Doritos and eat them. When he wants something he eats it all he doesnt save any for anyone. My mom spent $1,000 on groceries in one month. So now she is mad and wont buy groceries and I am so hungry and I know my brother is probably light headed as well because he doesnt eat as much as he should. All my mom or grandma does it make dinner but eating once a day isnt enough considering the small portion everyone gets. I can tell ever my grandmother is weak my mom made really gross rice and she was rushing to eat it saying you'll eat anything if your hungry. We tried sitting down and

If someone attacks me (my brother hits me playfully) my dog attacks me and not my brother. MY Grandmas friend was playfully shoving her and he bites my grandma.

Im doing a project and its with high schoolers i have to bring in african food what is something they would like
