I Just Don't Know What To Do

I was asked to go play baseball with my friends later but I am truly terrified to do anything physical with these. I am already scared to get my heart rate up let alone feel pvcs while my heart rate is up. I just do not know how to live normally with these. I have a lower burden but thinking of something bad happening while exercising is causing me not to go. Sorry I just wanted to vent and see if anyone has or had the same experience. I get my stress test results tomorrow so hopefully that goes well too.
