Re: nausea feeling
Question, have you tried seeing a therapist or psychiatrist? I know how you feel - you are essentially typing out the train of thought a lot of health anxiety sufferers have, but it's obvious you need to find some techniques to control your anxiety. It's leading you down rabbit holes and taking away your opportunity at enjoying life. I really hope you can find some help - I can understand why you do what you do but I think reaching out to a therapist would help you immensely.
