I feel like I’m always letting my therapist down , but I just feel so cornered when she wants me to go to group sessions ...

You wont always "succeed," and if healthcare professionals don't understand that, they have no business in healthcare.

Therapy is for you, not your therapist. If you dont feel ready to try something, you can try to work towards being ready, or try to recognize if it's for you or not. Personally, I think I'd hate group therapy. I've never tried it though. It takes time to learn and fully absorb new therapy skills, dont rush things just because you feel like your therapist is pressuring you. Theres a difference between pushing yourself to do better, and pushing yourself to things you arent ready for. If I were you, id explore with your therapist if this is something youre ready for. Whatever the case, youre not doing therapy wrong. Everyone is an individual and needs different things.

I agree with stf. The therapist is there for you, not the other way around.

I understand, I've felt this way many times before. When I saw a specialist, I felt like he was annoyed I was doing any compulsions ever, because it was an intensive program, and its success depended on how much work I put into it. I have to deliberately remind myself that I am trying to heal, not trying make my doctors happy. It's a disorder for a reason, and if all of the work you needed to do wasn't challenging, it wouldn't be a problem in the first place. As always, thoughts and feeling don't necessarily reflect the reality of the situation.

It’s just that when I call to reschedule and stuff .. it sounds like the lady is upset with me or that I let people down. I feel like I’m always sacrificing for other people. Like it aggravates me that they aren’t supportive of my decisions when I’m upset
