Extreme Breathing issue w/ mild tachycardia

Does this sound like dysautonomia? My symptoms are extreme shortness of breath, paralyzed diaphragm muscle, very shallow breathing, inability to catch breath, tingling in feet, and pinching feeling in neck areas. I also have some dysautonomia and tachycardia. I am unable to walk and talk and bedridden all due to the breathing issues. I also have had an active and chronic mycoplasma infection during the time my severe symptoms occurred. If I tried to over exert myself I would get into a very bad flare where I’d feel like I am suffocating and I’d be suffering for a long time, but my 02 on pulse ox won’t drop. My chest will feel very painful and it would feel like I don’t have oxygen. It feels like a version of chronic fatigue syndrome if it was only affecting my breathing because it doesn’t affect my energy levels at all, I feel fine, just can’t exert myself, and I have a suffocating feeling if I do. I constantly feel in fight or flight, and my neck area feels kinda sore all the time and very sensitive, and kinda stiff. We think it may be a form of neuropathy on my phrenic nerve or vagus nerve that has caused dysautonomia. Any ideas?
