Since 2 months,I feel weird. I feel really alone. I don't want to go to school. I get scared on the thought of going school and meeting people. I feel frightened talking to anyone. I want to sleep more and more. In morning I never want to get out of my room. i also feel physical pain in my body regularly.sometimes in my legs that i cannot walk.sometimes in hands etc. I feel no more excited about anything.My grades are going down and I don't know why I don't care about it. Please help.
