how can i tell my therapist about my ocd? i have it severely and it’s such a hard thing for me to bring up but i need help badly. any advice?

I feel like one of the worst things about ocd are the disturbing images or the ‘little movies’ that replay in your head over and over again. I have the worst sexual images with one of my family members that actually so bad that I can’t even look in the mirror. And it’s even worse that I have a lovely boyfriend and I’m so disgusted of myself that I feel like I don’t deserve him and I feel like I can’t be with him because of these thoughts, even he is the most precious thing in my life. These sexual images are so horrible and what makes it even worse that in these pictures I always see myself as someone who enjoys it. I know how to deal with this anymore. My mind is trying to convince me that that I actually like these images and thoughts and this is the hardest part, that I’m doubting myself. These images pop up in my head so naturally that I always question myself if I actually don’t like it why it comes so naturally or how can my brain picture things like this if I don’t like it. It’s getting worse day by day. It’s in my head 24/7, can’t concentrate on anything else, I can’t eat because I’m constantly throwing up. And my mom has to sleep with me every night because I’m so disturbed by my own mind. My parents know that there’s something wrong with me, they think I’m depressed but sadly It’s not something I can talk openly about with them. I’m seeing a therapist next week but I’m genuinely scared to open up about these thoughts that I’m having.

My name is Abbey and I’m a 14 year old girl struggling with OCD, I don’t like to say my OCD is severe but it’s the truth. I haven’t been officially diagnosed but I’m still being treated for it kinda via medication by my doctor. The reason I’m nervous about starting my therapy journey is I’m worried the therapist won’t understand what im saying or take it the wrong way and think I’m a bad person even though I know I’m a good hearted person. If you have any tips to overcome my fear of therapy please share! ✌️🧡

(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.
