Depression Forum - Am I Alone?

Hiya
im a 22 yr old student with no life, no ambitions, nothing. Ive been under constant depression over the past 2 years ever since coming to the uk. Ive tried to kill myself once, by taking 30 sleeping pills I bought over the counter. I didn't realise it wasn't enough, hence the rush to get me to hospital by my sister who soon found out. I really don't know why I did just that, n even now everyday, I keep on thinking of death as a way to get rid of this depressive feeling. I think about killing myself at least once a day - mostly thinking of jumping off my bedroom window on the 3rd floor, slashing my wrist, or jumping into rushing traffic. But usually im more keen on the bedroom window. I would usually drop a pence down the window n see how long it takes before the coin hits the ground. I always imagine how my family will cope with my loss, stuff like that. I really don't know why. Im a bit confused, whether it is the stress of my studies, or is it due to the feeling of loneliness n lack of support. Im really afraid bcos this depression is bogging down on me at almost every hour. I cant seem able to speak properly to people bcos the depression seems to seep through to my mind n it sort of clogs my eyes from looking straight. Ppl who look at me might think I look very sleepy. When actually its the depressed feeling that makes me look that way. This year, I have skipped almost half my university lectures. I dont seem to have the strength to get out of bed. My room is like a pigsty, im too depressed to clean myself up, or do the laundry, or talk to ppl. Im a reclusive. I dont want to be that way but there is nothing I can do about it. The gp has given me prozac last year but I felt it didnt do me any good. I still feel useless, unworthy, n I wish I can just end my life right away,but im always thinking of those who might be saddened by my demise. I have not contacted any of my old friends, bcos im afraid they might think I have changed so much n may look indifferent to me. I read depressing stories like prozac nation, n listen to indie like belle n sebastian, the smiths, stuffs like that. It makes me feel better to know that there are ppl out there just like me. N there r ppl who thinks like me. I really don't know how else I can cope with my studies in this sort of condition. I fortunately manage to pass my first 2 years in university just by going thru past year papers over n over again, but that will never make me a better graduate or a better person later in life. Im so scared. Whenever this depression thing starts to seep through my mind again, the palms of my hand n my foot will get very cold n sweaty, my mind in a state of despair, n all I can think of after that is suicide. The only way I can run away from attempted suicide is by sleeping. Yes, I sleep more than 12 hours a day for everyday of my life now. I want to get rid of this depression. But I can never run away. It is still there when I wake up. I usually cry at nights right before I go to bed. I have not made any friends during this 2 year period, bcos ppl might think me of a lonely antisocial creep. There's nothing I can do about it. Im confused. Is there anybody listening to me? Is there anybody who feels the same. I don't know. But who cares, nobody cares for me anymore. N nobody will understand my situation. Im still think of the 3 second drop from my bedroom window as an option. Sometimes, I wish I hadnt been born in this world. And now im blaming it on so many ppl - my family, my siblings, n especially myself. Im a good-for-nothing loser who cant even stand up for himself. medical question me
