I don't want to give my friend my personal information
Are you afraid he will look you up online with your personal information?
Yes, I'm not proud of myself and I don't want to be judged.
If he is your friend he should already know everything he needs too. I would be cautious if he presses too much for information you don't feel comfortable giving.
Yeah I want to tell him because I want to defend myself and make excuses.
You should not have to defend yourself to your friends nor make excuses.
