I tried joining sports and clubs to overcome my SAD, but none of those worked because I still felt that people were better than me. I wasn't a complete loner during high school; even though I had friends, it was extremely awkward because I also felt inferior... I've struggled for years with negative self talk and my family members criticisms seem to make things worse--I could never measure up to their standards even though I tried. That would explain why I feel inferior besides my upbringing. I read about negative self talk or your "inner voice" as your parents' or guardians' criticisms.
