It must be so hard for you to feel all these awful things.. my heart goes out to you..🥲
I have internal vibrations as well as terrible tinnitus & these make me very anxious.. & when I am anxious all hell breaks loose.. it becomes a vicious circle.. we suffer.. we want to cure ourselves so we become obsessed about getting the right diagnosis & we see many doctors.. pass many tests with no conclusive results which makes us even more anxious which brings on more worrying symptoms.
I strongly recommend that you try soft medicine to relieve your anxiety which could be the culprit; meditation.. exercise.. find a hobby you are passionate about.. enjoy time with friends this has really helped me. Good luck🍀
