Hi. :) You can totally overcome Social Anxiety Disorder because I did, actually when I was little I had a selective mutism. I never talk to people at school unless they ask me something, and when I reached grade 3.. 2 girls approached me and we all became friends :) The idea that having friends is a great feeling it made me think that I should change, so as years passed by I saw changes.. Little by little I became less shy. We can talk if you want ^___^ I am still shy but a lot lesser now :) I had friends now and I'm still determined to be more talkative. Before I never raise a hand but now because of my determination and belief in myself ..I can! :D
