Had my first erp session today and it was hard shall I keep going ?

(21+ ONLY: TRIGGER WARNING) I have therapy today and I’m nervous. I just started going to therapy and I really like my therapist. She talked to me about doing ERP and I’m really nervous about it. I’m scared to tell her the extent of my OCD, and my themes. I’m scared to tell her about my false memory OCD, because I’m scared that what I did was real and I’m just excusing it as false memory, although I have no memory of it. I’m scared that I am truly a monster and I’m using OCD as an excuse—and that she’ll find out and distance herself. I’m just scared that my whole world is gonna fall apart, all around me.

I'm just laying here avoiding being an adult and wondering if during ERP the therapists are mean. Like, is it a "tough love" type of situation? That makes me anxious

A few hours ago I had my first ERP session and I am currently feeling nauseous and nervous at the same time. Right after my first exposure I wanted to quit right then and there, but I know I cannot. Does anyone have any tips for sitting with this level of discomfort? Anything is appreciated. Thanks! :-)
