It happened again

I took the advice and propped myself up Something is wrong with me😭😭😭 it happened again like clockwork 3 am I am sitting up, I have two nasal strips on, and it’s still not letting me get air out of one of my nostrils. I’m doing everything right, I didn’t eat late. I felt the chest tightness before going to bed bc I was scared. Please someone help me

Can it be mold What can it be

This is torture
