Just in the past year alone, I've really been hurt by people I thought I could trust. It's something that has been going on all of my life. That makes it harder to get to know new people, because if close friends can betray me, there's nothing stopping mere strangers from doing the same. But I worry that I might come across as stuck up or something if I refuse friendship. It is just too hard for me to trust anyone new at this point in time. I want to be open and friendly, but the feelings of hurt are still just too raw. Am I rude for not wanting to open up and let new people in my life?
