In terms of voices you got to see a professional about it. I am not sure we can advice about that. What does your psychiatrist say? Do you need med adjustment?

With other things do you want to be healthy enough to be able to work or live alone or go to school or maintain good schedule? How do you see it?

I posted a list for you that has some basic daily routine that might indicate you are at least somewhat functioning. What did you think of that? Do you have reasonable sleep schedule? Daily routine? Do you shower? Do you eat at least few times a day reasonable amount? Do you do chores?
