If im anemic and have elevated cholesterol due to under treated hypothyroidism, what are my chance of having a heart attack or stroke?

Whoa: You're almost a grown woman. If you are anemic, it needs to be treated -- the cause needs to be identified first. If you are hypothyroid, your life is going to go bad unless this is managed, and the cause needs to be found as well. If your cholesterol is up, this needs to be managed as well. Don't ask "why is my risk?" but say "putting myself willfully in danger is foolish.".
