Depression is curable. Basically, depression is the unstableness in one's emotional and mental state. For stability to be regained in the life of the depressed, he must show some level of self help before anybody else can. He has to get himself out that state by deciding to engage himself productively. He must stay away from vices like drugs, alcohol, social media addiction, and any other thing that can't serve his mental and emotional state. Seeking professional help is also a viable option.
