Welcome to HCM
We understand your concerns
From the detailed description you gave, you are already aware that you have anxiety
about your health which we call as Hypochondriasis
. In a way by yout description I suspect that you are also hving Obsessive Compulsive Disorder
. Don't be sarcastic. You need treatment for these, not medicinal but therapies.
You need to change your lifestyles to suit your anxiety creating situations. First find a good doctor in whom you hve belief. Get all the tests done to confirm that you are pretty well. Then find a psychologist
or psychotherapist who can help you. You will be needing Cognitive Behavioral Therpy.
I can help you online if you desire so.
Get well soon.
