I can understand why OCD therapy wouldn't be a good idea during this ''situation''

At least I'm guessing it wouldn't be. I have OCD and also super sensitive skin grrr. I'm sorry you're facing this dilemma with your therapist. Maybe put therapy on hold for a while? I'm sorry I don't have any very good ideas. It's great that you're functioning but as you're not feeling well there is more to work on...
