how to cure my psychic illnesss MEDICINE PLZ?

I am so sorry to hear this, I wish i could help, im not entirely sure what you suffer from but if its depression try to talk to people , and get fresh air, understand that whatever negative thoughts you are having they are NEVER as bad as you think, even if you can see a negative outcome god is here! he will help, try to get your mind of things, our minds sometimes think of nasty stuff because we programmed them to think of the negative more, but if we just focus on the positive it will get better, there is always a good outcome to everything except death, if you feel sad with yourself and have deja vu, take a deep breath and try your best to see where you are, i am in a room, i am for example "matthew 19 years old" but with your name and age , and just go for a walk.
