Health ocd, Im freaking out

Please if someone can reply! I really just need someone to talk to. I don’t even know how to control my OCD. It honestly feels like it’s controlling me. Everyday my mind focuses on every bodily sensation I have and it’s like a broken record player, I have horrible health anxiety and my OCD just makes it worst just thinking about it everyday. It feels like everyone who I explain it to looks at me like I’m stupid/crazy. I use to be much more tame with my OCD, I use to eat things without worry, now I can’t even touch things I use to eat without worrying that I’ll get an allergic reaction (despite eating them BEFORE,,,but my mind tells me otherwise) and omg worrying about heart attacks, pulmonary issues..and I couldn’t even enjoy my own child’s birth because my mind was on high alert thinking I would hemorrhage any second or develop pre-E (complications of postpartum) I was miserable for the first couple of months of my baby’s life and I didn’t know what to do. And now, I’m pregnant with my second (4wks) and all the OCD thoughts and anxiety is coming back at me and I have no one to talk to, I feel lonely. And even if I considered taking a pill, I’d worry about being allergic to it and refusing to take it. I ruin everything for everyone. I remember I ate out one night and I started to think “you’re gonna pass out! You’re gonna pass out! (Without ever passing out before) and I had to leave! I feel like I ruin the mood for everyone when I don’t even try to, and I hate it.

So my OCD got that bad to the point where I’m barely having ocd and my body is stuck in stress, I can’t sleep, my mind is soo loud and my chest hurts and my vains are popping out and I feel like my body is shutting down what do I do ☹️ I don’t even feel like I am here I can’t focus on anything I’m always zoned out

I feel like my life isn't my own anymore. I live by OCD's rules. I can't ever switch it off. I spend most of my day mentally reviewing and constantly checking myself. I have to do things in a certain way or i dont feel safe. All this time that i've lost and for what? Idk how I let thoughts have so much power over my life and yet here I am. Every day. I can't even get away from it in sleep because i have dreams about it and I wake up anxious if i manage to get any sleep at all. I'm so over it all.
