Welcome to HCM
We understand your concerns
Well, we have to first distinguish between depression
and distress. Are you able to define and diagnose depression? Even experienced psychiatrists can't diagnose it properly. To make it simple, there are several tests available to measure the depth and type of depression, if it really is depression.
In your case, I think it is just a distress which is very much normal for everyone. Stress and obstacles in life creates stress disorder which then converts itself into distress. Some lasts for days and some for months. Let it get itself cover its course.
Otherwise, there is no alternative treatment avilable for mental problems. You must consult a psychiatrist
Wish you speedy recovery.
