What causes Depression

Lack or inbalance of a chemical in your brain called serotonin, which is the part of your brain that controls joy happieness and like I said if it's clinical depression your facing you may have some sort of shemical imbalance? I think the best thing to do about it is to see a doctor and tell him how you feel...chances are he'll probably throw you on some random anti deppresent and send you on your way or who knows you could get lucky and find a decent doctor. ,either way I wish the best of luck to you danoluma^o^

as far as I know, too much thinking of your problem can cause depression.
