Hmmmm... Right off the bat, the thing I can offer on a very general level is... well, a couple of things:
1. You are
worthy... of yourself. Define your own worth, and/or, self-worth. No one else gets to tell you how worthy you may or may not be. If you know in your heart you were worthy—then you were, and you are, worthy. Be worthy of yourself.
2. It's awesome that you know you are angry, still. I'm sure you're hurting too. You actually sound as such in your post... and sad, you sound sad, as well. My heart goes out to you. That you can identify your feelings—that knack, if you will, shall serve you well in communicating with others.
When shit like this happens in my life I've found I just gotta feel it, feel all of it, thoroughly. It's not always fun, more of purging kinda thing... sometimes takes a loooong time, comes in waves and all that. I always get better and come thru it, tho.
Venting helps, too... until it prolongs and morphs into the "same-fucking-story-get-over-it" vent. But you don't seem that way...
You can vent right here, if you need.
Best to you.
