Anxiety not stopping

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

TW I’m feeling really bad about myself today. I feel like a fraud and a liar. I’ve been unable to enjoy my time with my girlfriend because I’m bombarded with my thoughts. I’ve been asking for reassurance from so many people and nothing is helping. Nothing makes me feel better anymore and I’m worried that this is just how it’s going to be for forever. I miss when I could just be happy and not overthink so much. I miss being able to get through my days without this crippling anxiety. I’m worried there’s going to be a day where I realize I have no fight left in me

At this point I think I’m just tired. Took me a massive amount of strength to even type this. I’ve never had it this bad with anxiety depression and OCD. Firstly, how do you guys handle the trauma that comes with OCD. I recently realized Ive traumatized by own mind. I think this contributes to depression. Also, the thoughts frequency have gotten so high. It just literally jams its self in my brain. Before, I had some sort of control (at least a grip) but this days it’s so hard to try to get a grip. The unwanted feelings too? Omg, reactions that I literally can’t stand plagues me. My mind turns almost everything sexual. It’s crazy 🙃 Then the anxietyyyyyy! Wheew. I’m like a walking anxiety attack, my heart is always beating fast and it’s so painful. Working is so hard because I can’t get a grip, I feel so broken and I don’t think anyone can relate to this. I don’t know what I can do to help. Then the pressure in my head (that causes headache sometimes), sometimes I genuinely think I have a tumor! I’m pregnant so that makes it sadder, makes me wonder what kind of mother this beautiful soul is coming out here to meet. I don’t want to be a sad mother, and I cry more when I realize my child can feel what I feel rn in my belly😔. Another thing, the moment I don’t wanna do something, doesn’t even have to be anything bad. That’s when it feels my mind wants to force me to do it. It’s a whole lot and I’m just holding on to Jesus to help me out. At least he’s here so that’s comforting.
