I have the exact problem. I’m a bit older than you and am going through so much with my mental and physical health. My health anxiety started in my mid 20s. My biggest mistake was reading the internet. It literally has aided in my decline. Please take some advice from someone who’s walking the same path. Stop reading the internet. Find a good doctor and let him and God guide you. I’ve learned the hard way to lean on God. Please do these things before it makes you physically sick…because it CAN! Pray for wisdom and don’t lean to your own understanding. Btw I’m preaching to myself 😉.
