I keep waking up numb and just now had little to no oxygen to the brain, was seeing vivid stars.

No heart issues, been tested. But "asthma" isn't going away with Asthma puffer albuterol and a maintenance puffer. Instead taking very weary, short breaths. I can notice I'm not breathing much at all when I start to drift into sleep again.

What should I do? I'm a 22 year old otherwise healthy male with colitis as my only known health issue.
