In a funk

I'm in a funk over some personal stuff that is happening with my "friends." I feel betrayed, let down, and unsure of who I can trust. I wonder what it is about me that turns people off. I wonder if the people I've thought were my friends really are. I just don't know anymore.
I feel the need to find new friends, but that's easier said than done. And I don't want to seem needy. I've recently become friendlier with a few new ladies and I hope that matures. But I worry that I'll seem to needy, or seem like I'm trying to bust into their friendship and it will all blow up in my face.
These are the times I wish I could just curl into a ball and forget that other people exist. It's sometimes easier to not have friends than deal with the hurt that they cause you.
