Friendship...

Hi so my name is Kimberly and I'm 23. I current have maybe one friend who I can call my own I would believe (even though we rarely talk). For some reason I can never hold on to any friendships with people. I know I burned down some bridges with some and others have burned down bridges with me, but I honestly don't know what to do anymore. I want more friends, but I feel like every single time I turn around they are gone or I talk to them less and less. Am I the problem? I feel like I am.
