Hiya lonely!

I'm so sorry about your health problems. It must be just awful to live in a constant state of ill health.
It sounds like you've sought medical advice, and probably lots of it. Don't give up and don't feel defeated! I'm sorry that I don't have answers for you, but please allow me to suggest that if you are spiritual, take a few moments each day and just rest in the arms of God. Ask that He provide you with comfort, healing and physical restoration. Have faith!
