It seems you have a lot of reasons to be upset, but anything you have been diagnosed with does not define you. You are your own person now and whether or not you want to forgive your mother is up to you, but you can now express yourself however you like and she no longer can control how you feel or act.

It is easier said than done, but I've personally found that holding a grudge is only going to exacerbate your rage and insecurities.
