Hi Kenny and welcome!
Your story and mine have many similarities! I too am doctor phobic, and am long overdue for my regular check ups and tests. :/ Therapy and self help have allowed me to not be overwhelmed daily by health anxiety and panic...however, I still have this last hurdle to clear...of getting over my fear of going to the doctor's.
Have you considered therapy and or medication? How about
self help? Hibee mentioned the Resources here. They have great material...and even links and book recommendations specifically for Health Anxiety...all of which are great treatment options.
It is a process...one that I am still journeying through. Stick around and we can all do it together with support and understanding.
Talk soon,
Scaredy Cat
