Hello there and welcome to PC.

Sorry to read of your background. The only thing I can recommend if you can is to go back to therapy. Am glad that the brief sessions helped understand some of your problems, but perhaps it would be beneficial to keep working on it, perhaps some CBT. You've a lot of issues to work through with your childhood, and you had a really tough time to try and make peace with. Am sorry that these things happened to you.

I think its excellent by the way that you can hold your hand up and admit your obsession mistake, personally thinking that being able to admit something is broken is the most important step to fixing. It takes a lot of courage to admit fault. I think now that therapy may just be the helping hand you need to learn methods to cope and understand some triggers you may have so that the next time you have a relationship you'll be able to recognise some feelings and perhaps not act on them.

I also think that perhaps you should have a little break from dating. You already know its unhealthy to obsess and unhealthy to depend on someone for your happiness. Perhaps, if you do go to therapy, that you could also concentrate in making yourself happier in other area's. Going out with friends, making you own life more fulfilling and, well, basically having some independence so that you will not rely so greatly on your next boyfriend so heavily for your own happiness.

I do wish you very well, and I hope that you get some help soon.

Hugs.
