I get very depressed when I think negative; I want to change my thinking to a better way. I never think positive; I have really low self-esteem issues, social problems, and I put myself in super-hero positions. I often get confused who's in charge of my life; That's God, but I think I'm in control. What are somethings I can do to change my thinking, bring up my self-esteem issues, and help my social problems?
