I do it also

It's what other people have posted... I had a lot of love and care and then the person abandons me. I just can't trust that things will remain stable. So if there is even one thing that seems to threaten the relationship, I panic. It's dumb. I know I'm doing it. But I can't let the feeling go w/o some sort of reassurance. I will either push my T away or emotionally beat myself up till I know that everything is okay again. And I constantly need reassurance. It's irritating to both me and the other person.
How to stop it? No clue. I just keep bringing it up over and over and over again. I'm hoping one of these days my brain gets it and knocks it off
