Please any past students or teachers help!! 

last night i was lying in my bed and looking at the ceiling. all of a sudden i felt myself lift off my bed(like going up the hill on a roller cover feeling, then all of a sudden dropping down to my bed.ive always been interested in birds flying and aiplanes,so this felt scary but amazing. I wanted to make sure it wasn't a dream so i stood up and locked my door.and lied back down and relaxed still so nervous and shaking. then i could control how i flew, i literally flew out of my house and over my neighbourhood like in peter pan or something. Ik i sound ******* crazy, After about tirty seconds i lied back down and was exausted so i slept.i haven't thought about it a lot because nothing spiritual or anything of that kind has ever affected me. I haven't told my mom because I feel weird talking about it, the emotions were real, it really felt like i was going down like in a roller coaster or those falling rides at disney land. im 16 and confused,AM I SICK?

OK listen before getting into it, i don't want people immediately saying I am because Molly is stereotypically SUCHH A BAD DRUG and will kill me with one blow. Like I don't want people replying who don't know anything about the drug and aren't going to be reasonable.

Here are the facts,

-I do molly at parties (so atleast once a weekend)

-I will OCCASIONALLY do it on a school night if i go out, or if im having a horrible few days (Occasionally 2-3 times a week , including party nights)

-I dont get cravings when im not on it

-only time im tempted to do it as a craving is when im EXTREMELY upset.

-Ive been doing it since end of summer

-Im still growing,and learning about myself and experementing (im 17)

-my life has been extremelt unlucky this past year,with alot of ****** up **** happening to myself and my city this year so ive been going through alot.

-My friends are constantly worry about me and call me a horrible influence even though ive never made them do it,they have never done it with me.

My one friend told me i should quit and she talked me into it, i went 8 days, then did it , not because i craved it, because i felt like having a crazy party night.

Are they over reacting? am i genuenly addicted or is it them over reacting because they have never done it.

My boyfriend of 1 year went on vacation for two weeks, the first day he left his friend got drunk with me and told me all about how he cheated twice. He had sex while blackout drunk with a girl,and kissed a girl while drunk. When i figured this out i was completely destroyed , as this was the first boyfriend I've been with who i never thought would cheat in a million years.

for the next week i kept it to myself and didn't tell him as i didn't want to confront him till he was on irl.not over phone/text.

One night i went out with friends, was clearly hurt over the cheating, took some MDMA got drunk , and ended up making out with one of his friends. No one but me and the guy know.

He's coming home in a week, do i tell him or not.

"Poetry lifts the veil from the hidden beauty of the world, and makes familiar objects be as if they were not familiar."

We both decided a break would b good but just from dating, not from being loyal.SO I STAYED LOYAL even though i was offered many chances to not.About six months ago he cheated on me with two girls and asked for nudes. I forgave him and he begged for me back and he felt so bad. We have been fighting aot during this break because i have been going out with friends and he has been staying home. This girl he used to talk to texted me and told me that he had privately messaged her and got her snapchat, then flirted with her and asked her to meet and and asked if "he should bring a condom". there was proof of it so he addmitted it.he said he only did it cause he was alone and worried i was going out and doing the same thing. This whole break he's told me he only wants me, we still went on dates and had sex. Ive dated this guy for a year and i know he's in love with me and I'm in love with him. Im terrified that if i break up with him fully ill be alone for years. Im in high school and have basically no friends that i love as much as him. I just feel so horrible ditching a 1 year relationship. Please help me, I'm so confused and alone.

im so unfair to my bf cause ill start crying over the finest things, ill get jealous WAY o easy, ill freak out super fast, and if i don't express my anger over something ill just start crying to myself and be stressed. Ik I'm over reacting about a lot of stuff. HOW DO I STOP

-In the photo it shows the brown dead

SO i was taking a bath and using a towel to exfoliate (like i always do!!) usually i just see some dead clear skin come off. Today when i was doing it today Brown skin came off,BROWN,but only the bottom half of my body had this.Arms and breasts up it was clearish (like normal). Im white but am naturally really darkly tan a lot in the summer and lose some in winter. IVE already lost my tan (i also dontthink its even possible for a tan to peel off like this) and its never happened before even though i tan every summer. Please help I'm genuinely worried its the actual pigment leaving my skin and ill lose my colour. PLEASE HELP

Ive been dating my boyfriend for a year and we are both 18.About two months ago i started smoking cigs 3ish times a week.Im not addicted but i do enjoy the act and feeling of smoking. Hes smelt it on me twice but just covered up by saying i was sitting next to someone on the bus that reeked of smoke.He always has been against drinking and smoking.I don't want o stop because its relaxing so should i tell him or just keep it to myself?

Every time i lay straight with my legs stretched out to sleep i get a pain,like a throbbing or growing pain in my left foot.the second i curl up or move my foot it to another position it goes away.It only happens when i stretch out so it couldn't be an injury?Its been like this for two weeks and its getting really annoying because i cant sleep in that position!

I like this guy and he wants to date but he's had sex a lot,and I'm not so sure I'm ready or even want to.And if i tell him that,it will only postpone him asking.Also my best friend says he bullies her bus she's known for lying and theres no proof.
