I just want to me normal again

For a couple of years I have been hyper focusing on my health to the point I bought a o2 censor, personal EKG, Blood Pressure Monitor, glucose monitor, thermometer. Literally the whole hospital. The moment my pulse goes above 90 I feel like I have to check everything, it’s a whole routine. When I eat something like today I had skyline chili of course that is going to raise all the levels but I panic and throw it back up and drink a cup of prune juice to clean myself out. I feel like this all started when I got diverticulitis from putting Splenda in my coffee. The doc told me to eat fiber so I literally ate a bowl of fiber one cereal everyday and it completely healed. I just get to worried about my health, I think healthy M/ 29 years old and 190 I also golf regularly. I just can’t bet this darn anxiety about my health.
