Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.
That ends one problem. Then, of course, the idea is to correct that behavior ... whatever it takes .... so that you can have a normal life. That probably means professional help. I THINK it is better to have ONE problem (SAD) than 2 or more problems (SAD/abusiveness).
Minimization ... more or less, is the idea.
I would guess you might find it easier to avoid making new friendships for the time being, but with proper support it doesn't mean that would be forever
