I think maybe you should try a different therapist. Sometimes it takes another try. If you could sort things out and even slightly get more comfortable in social settings…that will help you so much.
My cousin resisted for years and his parents told him they wouldn’t let him go away to college unless he tried for an entire year before. it really helped him a lot.
and don’t simplify whatever problem it is… such as having your “own space” it is more complex than that. I think you would greatly benefit from trying again.
You have your whole life ahead of you but first you need to take care of yourself i order to succeed in whatever career you choose.
