Hi, I Am Wondering If I Should Go And See

Hi, I am wondering if I should go and see a doctor as I have been diagnosed by a nurse with hyper mobility (Elhers-Danlos Syndrome) in my GI tract. I am on a special diet, I have been taking supplements of Vit C for collagen, and friendly bacteria. I feel really tired, battle with constipation and lack of focus. The doctors never could diagnose anything wrong with me in the past, it has been a life-long battle, I am 61 years old female.
