Hi Teafruit. I’m sorry that you’re going through all of this! It’s really a shame that you had a bad student therapist inflicted and had such a bad start with therapy.
I am wondering why this therapy is ending right now - is it one where you are only offered a certain number of sessions?
I also wonder whether it would be possible for you to look for someone who specialises in OCD, or ask your doctor about this, as they might have a better understanding of what would help the most?
