it sucks i know exactly how you feel. i isolate myself because i fear of being ignored and humiliated. im only 15 and a big reason i have depression is becasue of the girls at my school, and the people that are suppose to love me. simply girls are b*tches. you cant let anyone fase you, im doing better becasue i realised that the people that want to help you will, and the ones that dont wont show they care at all. i wish i could sit in my room all day in the dark then be with people, im actually scared to go to school, when i leave my house its almost like its to much for me to handle, all the people, i think its social anxiety. sounds like you might have it, im getting help from a counsellor, it helps me alot you should try it if you dont already have one.
