Hello and welcome to the forum. I'm sorry you're struggling with this--it sounds pretty intense. I found, personally, that my relationship to my T felt more secure--That I was less jealous, less worried, less obsessed--the better my life outside of therapy got. As I became closer to other people, I no longer needed to feel close to someone I could only see once a week. As I got into hobbies, projects, and meaningful work, I no longer thought about the little ups and downs of therapy.

So that would be my advice--get out there, meet different people, work on your existing, non-therapy relationships, and find something that makes you feel good and good about yourself.

Good luck!
