Sleep deprivation can be deadly sure but you kind of have to really work at it.
I'm trying not to overblow the OPs symptoms. I will add to the OP you should see a doctor. It could be anything. We often tend to sort or associate correlation with causation.. It could be
vaping, it could be the start of lung cancer from years of SMOKING. I'm not trying to scare you I am just saying....
See a doc
