I never really was crazy or hyper but was much more outgoing a few year ago then I am now. Thoughout junior high and highschool I hang around with the same group of friends almost everyday. Use to hang out with a group of like 20 each day (was good friends with 5 or 6) play basketball walk around town etc... Now I am lucky if I can find a friend to hang around with and spend most days alone.
Your not a failure if you still have something to prove.
Keep your head up and hope for the best, Things will hopefully start going your way
