You need to spend your time doing something you want to do, do you have any hobbies. Is it because you are unemployed that you are depressed. A job should not be the only source of happiness available, because it only seems to stress most people out. Read a book, listen to some music, I don't know, it is impossible to answer a personal question that is kind of vague and impersonal.
You know stressful life circumstances can trigger episodes of shizophrenia and other mental diseases. Even if you are unemployed find something to keep your mind busy. Don't let it to be a devils workshop. Do lot more positive things and be happy!!!
