Hi TiredOfThis2008
Welcome to PC. I had the same problem with relationships (friends and intimate) 15 years ago. I found with regular individual therapy, and then DBT (dialectical behavioral therapy) several years ago, I have been able to let go of some of the same issues you are having. Difficult? You betcha, but I am much more at peace with myself and everyone around me (almost everyone, LOL). There is also a site that may enable you to try some DBT skills out also, if you are interested.

Best of luck, and let us know how things are going
