SA has caused me to be depressed.
The handicaps it places on the quality of your life so early in life mean depression will naturally follow.
When I was 16 I never felt there was anything of any major significance I had missed out on in life - sports, friends, family, school were all fine.
But after as the avoidance kicked in to deal with my anxiety I knew I was missing out and I knew I would regret this down the line.
Enough to make anyone depressed!
