Being overly aware of your sensations is hell

Does anyone else struggle with OCD when it comes to breathing? I've had this for about two years now on and off and finally had enough and came on here to say this. When I try to explain this to other people, therapists, etc. they just don't get it, so maybe someone on here does. I literally cannot stop thinking about my breathing and when it is at its worst, the very act of breathing feels incredibly uncomfortable. It feels like the walls are closing in on me, I constantly feel like I'm having to catch my breath, and I constantly feel the urge to take a giant, "complete" breath and that is the only way I feel comfortable. It's usually manageable during the day, but at night when I try to go to sleep it's awful because when my brain has nothing else to focus on it reverts to the breathing. People tell me to just stop thinking about it but I literally cannot. Can anyone else relate or am I all alone on this one

I started dealing with OCD when I became fixated on health issues, particularly the fear of contracting a life-threatening disease. If I experienced any kind of medical symptom, no matter how small, that even remotely hinted at something potentially fatal, it would drive me crazy, and I couldn’t stop obsessing over it. Then one day, I started having intrusive thoughts about accidentally hitting someone with my car, and I would end up driving in circles to check if I had. Eventually, I found myself overwhelmed by a flood of new obsessive thoughts and compulsions. One day, while I was at the park, a squirrel came near me, and for some reason, I felt like it attacked me. I Googled it and learned that squirrels could carry rabies, which spiraled me into a deep fear of rabies. I became consumed with the thought I received a bite from a squirrel, raccoon, or bat any time I’m in areas that trigger me. It started off only being inside then transferred to even being in my own home. This made me obsess over every physical sensation in my body, compulsively checking to make sure nothing was wrong. One compulsion that I hated the most would to be putting rubbing alcohol on me to make sure that I had no open wounds. Every day feels like I’m walking around in a fog of anxiety, constantly worrying that I won’t even make it to old age. Sometimes, it gets so overwhelming that I just want it all to end. It stresses me so bad at times to where my brain feels like I’ve been studying all day.

I can't live with OCD anymore. It's ruining my life. I feel like I'm being constantly bullied in my own mind all day everyday. I don't know if what I think and feel is ever real or normal or okay, what is me and what is the OCD thoughts. I don't know if any of my experiences are normal. I'm exhausted from picking apart every single conversation I ever have with anyone until I'm strung out by a vague and ambiguous feeling of guilt. I'm tired of feeling like I'm a bad person and feeling scared all the time and not knowing why and having my brain spin me out on an endless spiralling train of thoughts that never goes anywhere and just makes me feel disconnected from everything and everyone around me. I don't know what I feel and if what I feel is normal or if anything I am doing is real and actually me or if I'm 'losing my mind.' I don't even know if this makes any sense. I get into these states of mind where every thought in my head and everything I feel and perceive makes me question my own sanity. I don't know if anyone likes me because I have absolutely no concept of what I am actually like. I feel completely lost and confused CONSTANTLY.
