Hi AM and welcome!
Well, know that you are not alone...and that you have come to the right place.:)
There are so many of us here with the same concerns. Health anxiety is a topic that comes up here again and again.
You mentioned medication...have you sought other forms of help as well? Therapy and self-help are other options that you may want to consider...along with talking to your doctor about
the possibility of re-visiting Rx treatment.
We have a great Resource Guide here:

Inside you will find lots of great ideas on how you can get started on managing your anxiety with self-help tools and techniques. There are coping exercises...as well as book recommendations and an article/link specifically on the subject of health anxiety. (if you have trouble locating them in there, let me know and I'll glady supply the direct links for you.)
Keep posting with us as well. Support is key for recovery, and we understand and care.:)
Talk to you soon,
Scaredy Cat
