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.

Anxiety is a pig of a thing - I have had the full on panic attacks when I was at my worst point in my depression journey. I still get anxiety from time to time (like today, for instance). But I can tell you that it does get better over time. I personally haven't had S.A.D but I do know of people who do suffer from it so get outside as much as you can. And keep coming here - I have found a lot of comfort and support from the people on this site. I don't sign in very often, but when I do, I always feel better.
I agree with Tired - see if there is a counsellor at school who may be able to help.
Hugs to you!
