You worry way too much. It's practically ruining your life. If there's anything bad that could possibly happen, you've worried about it. Chill out a little, and realize that life is pretty great as is. Sure, things may go wrong. But if they do, you will be able to deal with them.
You empathize, talk things out, and express your emotions freely. You're a good listener, and you're non-judgmental with your advice. Communication is how you connect with people. You're always up for a long talk, no matter how difficult the subject matter is.
