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 a good start would be a medical check up ... thyroid levels, etc ... make sure there are no systemic problems. Then address the depression/anxiety issues ... medically speaking. Once that is ruled out, you know where you are .. if ruled IN, you can get treatment. It is widely accepted that depression (clinical/maor) cannot be treated by one's self. Talk to a doc about it.
>>I've lost most contact with friends.
You have 3 choices .. resume contact, make new friends, both.
Depression in youth is serious .. because it destroys one's life ... if untreated. Get yourself some professional help .. it is treatable.
