Dealing with Schizophrenia help:?

I was diagnosed with the mental sickness when I was 18 years old, I used to misinterpret things people say and do, and started doing strange things around the house when my Schizophrenia showed up, had a relapse and heard voices of people talking to me which their voice's where all different.

Now I am 21 and I hear voices like my head is a radio, and the voices Even comes from people I know like Outside of me and I hallucinate allot everyday, Now I had I want out but don't know how, I take the strongest medication there are but nothing works, the voices I hear is like allot of conversations going on like the person or persons are bedside you, this goes on while I am awake and I hear music in my sleep.

What is wrong with me should my sickness be that bad?
