Two big emotional problems. I need to work through them. Please help!?

I am claustrophobic around people. It terrifies me to be in a large crowd and I usually prefer standing off to the side to avoid being near others. What I learned to do what turn my fears into my likes. Instead of saying I'm afraid of this... I say, I like this... I want this... I still have issues to this day, but thinking in that way, it helps me be less terrified and helps me face my fears of being near people. About being emotional, tear down the wall and start being more honest with yourself and your friends. You owe them your honesty and they should know your true feelings. If something is bothering you or hurting you, wouldn't it be nice to pour your heart out once in a while with a few tears? It relieves a lot of stress and also helps when your friends support you and give you feedback/advice. It's hard to do this for people who are closed off, to me it would feel like maybe I'm not worthy enough to be their friend, so that's why there's this barrier between us. If you've got true friends who want to be there for you, don't expect them to give you their all when you're not doing the same.
