I had a weird episode with voice in my head and stuff, never had it before so i went to the doctor, etc etc

After a week it suddenly stopped, but it appears to be that my body couldn't take that crap and depressive episode started. I had something like that before, so I struggled, I fought, every cooked meal was an achievement for me, etc etc  
i have no money for meds, for doctors, I think i could at least stop this episode at the other time, but i need to recover FAST. I have exams, a lot of stuff to do, my life is ruining right now! Why would voice have annoyed me now?   
IS IT EVER POSSIBLE TO RECOVER FAST? please tell me, i am crying of desperation, all my struggles are for nothing if i fail everything... It will get worse.  
Nobody understands me, everybody around me saying that i'm faking it for attention, everybody ignores me for the sake ''not giving attention". I am trying to get this alone, because i did it in the past. Why it's harder now? Friends trying to understand me, but it is so weird. Like please, tell me something good or bad about me, SOMETHING, i'm losing sense of myself, i don't feel i exist. They answer anything but something about me. I wanted one thing, just one thing to help me. I try harder and harder every day, but that's stupid, it is getting worse. Why my efforts mean nothing?   
How to help myself, most importantly FAST. I don't have time or money for this NOW! Why would voice annoy me now?    
I am so sorry, i know nobody will help me here. I know my language is horrendous and i become more and more unable to think properly. Just answer one question PLEASE:  
How to help myself, most importantly FAST???
