I have a lot of loss (and abandonment) issues. All goodbyes hurt if we've cared about someone... But if they are abrupt and I don't get an opportunity to say how I'm feeling, then they hurt more. This has happened to me with a therapist and with a couple of good friends I cared about. I know it's most likely not about me as much as its about their "stuff" it just really hurts when it's someone I was starting to trust (like a friend IRL who I thought I was getting to know and who I thought cared about me.. I (or part of me) goes back to feeling worthless and that I deserved to be mistreated and hurt
