In hospital for fracture. Given two kinds of BP med instead of one. Is that why I feel like I am dying?

Ask docs/nurse there. You have access to doctors and nurses right there, why not ask them. They know what meds are given and what side effects can occur. Also, i assume your are on pain medicines too..Maybe that is what is causing your symptoms of dying...Pain medicines can cause strange feelings..Altered perception/hallucination/high/low etc... Good luck.
