Fix your mind and stop running around looking for who will cure you of depression and sadness.

Nobody CAN cure you. You're the problem. Fix yourself and depression will go.
If I were you, living the kind of life you're living (broke, lazy, purposeless, no ambition, no passion, no skills, not competent or good in anything, nothing built inwardly or outwardly that commands respect and admiration, etc) , I'd still be sad or depressed like you are.
