I had a huge pulmonary embolism nearly 2 years ago and have scarring on my lungs. Still nearly 2 years on I can’t do much like I used to. I get so tired and can’t breathe if I stand too long. Hoover, walk. Anything really. I also feel dizzy if I do too much. Sometimes I feel I’d rather not be here than feel like this all the time. Having a bad day today. Does anyone else feel like this?
