I'm leaning towards the "needs psychologist" part. I was stuck in a rut from my own bout of hypochondria for pretty much all of 2021, it was not fun. The constant feeling of impending doom and everyone dismissing my problems unfortunately gave me suicidal thoughts like crazy. I eventually sought therapy and it helped a little bit, but a lot of it just went away on its own.

OP, it does get better overtime. Quit looking up symptoms on Google (or other search engine of choice) and drink plenty of water.
