If I just let them be thoughts and not give in to them then will they reduce? How can I get them to reduce? I feel like my ocd is attacking my family members now like my mom and grandma and I feel so ashamed. How can I make this all go away?

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.

How do I stop letting my intrusive thoughts control me? Ive been having them for almost a year, once I graduated, become more isolated and lost more friends they've become worse. I feel like when I had friends and was still going to school they weren't as bad probably because I was living more so I didn't take them as seriously. But now that Im home all day and alone they've gotten worse and it feels like they're starting to control my life. Theres times where Im on social media and eventually I forget about them but then when I realize I forgot about them they come back. Sometimes the thought just lingers it doesn't even just pop in my head and go away. I can't tell anyone in my family because they'd judge me for the thoughts and they don't really believe in mental illnesses. I also sometimes think of what other people may think of me if they knew the thoughts I had and it makes it worse. How do I stop letting these thoughts control/trigger me and stop reacting or feeling some type of way about them.

My OCD has become so bad and I feel so alone. I have religious OCD (Christianity) and I’ve been doing okay with letting the blasphemous thoughts go in the moment, but I’m so overcome with guilt and shame I can barely function. I can feel okay and hopeful for a few minutes and then I’m reminded of the horrible thoughts and how nothing can take them back and I can’t handle the guilt. I’m becoming a burden to my family and feel so alone. I do not know what to do. Please help.
