Prayer and Jesus DO help depression, but like all other medical conditions, it needs to be thoroughly researched as to the root cause. Is it a brain chemical imbalance? Is it the cause of some emotional trauma? As a Christian, I'll say some depression is caused by sin and refusal to repent or to make something right with someone else. To say ALL depression has one cause is short-sighted and does countless amounts of harm to those who are depressed.
Depression is controlled by medication , not religious thought. It is a serious condition that can be controlled thanks to science.
I know several but it is controlled with medicine. I do know one that attempted suicide, unsuccessfully...thank God!
Everyone knows someone who suffers from depression. Not everyone who suffers from depression lets people know they are affected.
Depression is not a moral failure. It is an injured brain, often from an imbalance of naturally-occurring body chemicals.
Go to church, pray, and love your neighbors, family and count your blessings each day.
