BREATHING

PLEASE HELP!! I’ve had anxiety for the past 5 years or so. I also have somatic OCD where I’m very focused on my body sensations. The worst sensation for me is always noticing my breathing, this is what I’m asking help for. I always feel like taking deep breaths to satisfy my chest feeling and sometimes it’s successful and sometimes it’s not. This breathing thing has been taking over my life I can’t work or do any activity my mind just wants to manually breath at all times and I end up hyperventilating with dizziness and almost feeling like I’ll faint. Idk what to do anymore I want answers why does this happen can this go away?? I’m so frustrated it’s so tiring I’m slowly giving up
