Im lost.

my life my life my life damn

so im 18 years old left high school with 8 O levels 5 Bs and 3 As

my mom believes im a failure cause i didnt get into university because they said that i only have 5 A levels and they need 1 more.

i am assuming that yes im a failure cause i did 5 A levels in one go but i got C for everything.

she believes that i spend too much time playing video games and watching television when i merely do those stuff for like 3 hours a day and i study for like 8 hours a day.

i accepted the fact that i need to do one more A level but quite frankly doing one is a waste of time so i am doing 2 but she is constantly preaching that her friends children are better than me and i will not amount to anything unless i leave games alone and study 24/7.

now granted i am also doing a pre law course along with the 2 A levels so maybe im in over my head but for gods sake man its like i am absolutely useless in her eyes and she wishes that i was born a female as males are too lazy and useless.

so my question to you all is:

what exactly do you believe i should do in my situation cause quite frankly i feel like i should just quit and find some minor job to leave my house and live alone and have some peace of mind?

anyone know any good ones apart from rurouni kenshin and peacemaker O_O itd be a good help thanks alot the good people of yahoo ^_^

:D

are my ideals good?

I believe guys should stick to one girl and love her for all eternity never cheat on her and just be committed for life. i dunno if its right cause i was like that with this girl i like and she hates it she is afraid to commit so do answer this what should i believe in and dont say god >_>

i really like this girl i told her she said she cares she ignores me sometimes and says she isnt in a "talkative mood" so i didnt pay as much attention as i normally do and shes like one word answering me and is like giving me a stingy attitude so what does that mean and what should i do help plz?

xbox 360 or ps3 which do u like more do tell?

ok so theres this girl i like so damn much and i didnt talk to her today cause i felt depressed that she merely wants to be friends or close friends and not my girl and i talked to her when i got home she was like hella pissed saying i dont know the huge effect thats had and we are back at square 2 if i wanted to make progress with her i should have not done that, when she pisses me off i just be quiet and she always comes to be nice and touch my hand and say shes sorry or whats wrong but the one time i dont talk to her all she gets pissed and doesnt really want to speak to me anymore or she cant manage to shold i stop wasting my time with this girl cause ive been telling her how ive felt for like 3 months now and shes all like shes afraid to be close to ppl she doesnt wanna be together cause she will get hurt HAT SHOULD I DO PLZ HELP CAUSE IM CONFUSED MAJOR YOW

i was aggravated at this girl today for like totally hugging other guys when she well and good knows i like her she doesnt give a darn about my feelings to an extent when we are at school but when im at home and she reaches home she calls and said shes sorry should i put up with this or just not talk to her?

i told this girl that i like her im doing my hella best tobe truly honest with her but she CONSTANTLY brings up her ex bfs and how imma hurt her and let her down and some other rubbish its so irritating do u think i should just give up and ignore her or should i try to stick to my feelings and be her friend and never mention i like her alot again do tell cause im hella lost here.
