What happens during an episode of OCD?

My OCD has never been this strong, it's so real, it feels like it will never go away, it's never been this strong for me and it's very scary.

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.

I don’t know how to deal with the thoughts that come and barely gone. Usually, the brain often remembers and forgets things. People with OCD however struggle with trying to forget the intrusive thoughts because of the imbalance trying to convey what is real and if the thoughts in your head will come true. Just for the past few days, I was having fun and suddenly hit with a wave of obsessive thoughts and making me stuck with nowhere to go.
