Bedtime rituals

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

So, if I'm retelling a story or relaying information to someone, after I'm done speaking, my brain will send me thoughts like, "What if you lied? You might have told the story wrong! You're lying!" I've started second-guessing myself, even when I know I'm not lying or telling the story wrong😭 This has also bled into twisting my intentions behind certain actions... For example, the other day, I'd been babysitting my younger brothers. I'd gone to use the restroom and thought, "What if the door isn't locked or closed all the way?" Because this has happened once in the past. Turns out, it didn't lock correctly, and one of my little brothers almost walked in on me, but luckily, I shut the door in time, and we laughed it off. But then, I kept getting thoughts like, "You knew that would happen, and you didn't double-check! You wanted that to happen and for him to walk in!" :( I know this isn't true, but it's so annoying! Has anyone dealt with this? If you have, do you have any advice on how to deal with these thoughts?

I have pure ocd i think , i always gotta make sure i do certain things like tap things , light switches on n off , shut things few times and re open them till it feels right . Walk in a room go back out and back in out in in till my mind is right Its exhausting
