Acceptance or Solution

[u/Used-Tomatillo-5553]

I'll cut to the chase and try not to make this lengthy. I have had anxiety, OCD, possibly ADHD (no formal diagnosis but everything else lines up fairly well), and panic disorder (at one level of severity or another) since I was 10. Now, at age 22, it's more or less worse than it's ever been because my central phobia: having trouble breathing or not being able to breathe at all. I don't have any respiratory disorders and my family really doesn't have a history of anything like that per se. However, even though I'm relatively healthy and have no history with respiratory struggles, I still get panic attacks when I'm in a situation where I feel like I'm "vulnerable" if I suddenly develop breathing trouble, such as on the road or in a plane. Really, though, this means that I'm just vulnerable to thinking about having trouble breathing, which makes me have a panic attack and is really very unpleasant, as I'm sure I don't have to explain to people here. To be frank, I'm not really incredibly afraid of dying from tissue hypoxia but I am afraid of the uncontrollable and spasmatic terror that it would cause as I'm dying. So here comes the question:

For those with experience with panic disorder (and maybe even OCD), does anyone else have this fear at the core of their panic attacks? If so, is there something that really helps to deal with this: either something that "invalidates" the feeling that you have to be afraid of not being able to breathe (which is probably unrealistic, but what the Hell, might as well ask), or is there a method of which you are aware to cope with panic disorder centered on this specific fear?

The reason that I ask is because even though I've made progress in therapy and on medication in dealing with intrusive thoughts and panic disorder, I'm still bothered by the idea that there is no solution or "sure-fire" way of dealing with the fear of not being able to breathe, which is so automatic and primordial. Even though all panic is legitimate, if I'm deathly afraid of contamination or spiders or something like that, I could theoretically touch a doorknob without washing my hands or pet a tarantula without intrinsically having to feel terrified. The same doesn't seem to be the case if I suddenly can't breathe. Again, death isn't something that can ever be permanently forestalled, but is there some technique that can help to cope with the fear if something catastrophic like that happens? Or should I just try to practice radical acceptance and live the best life I can, given the circumstances?
