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.
I think you need to make sure you have a job, and a house, and then make friends with people you get along with. Watch who you call a friend. If they're avoiding you, they're not your friends.
So if you have no friends you need to develop interests, meet people, have a good time.
