I know this is going to sound crazy, but taking some sort of martial arts might help you. It will get you exercising like you need and will also boost your self-esteem.
i cant look at a person straight in the eye. i am so insecure about myself. once people told me i looked pale, this brought about panic attacks that really disturbed me and ruined my day. thinking that i was sick, dying or something. anyone out there with the same problem i am facing? i just cant seem to overcome my fears.
