I hope it's that simple. I too have most of those symptoms and have for about a decade. It was those symptoms I reported which made the doctors put me on Vitamin D so for me it wasn't the cause. However each time my doctors gave me something to treat my symptoms, they just seemed to get worse and I too would then blame the meds for causing the symptoms I had before starting the meds.

Many of the symptoms you report in your threads are things I battle. I went to doctors for years thinking I must be dying to be so sick. Many doctors and opinions and tests later in still being assured I'm not dying and my issues will not kill me. I'm not saying this is the case for you but for me, stress and anxiety make me horribly sick. My gut is like a second brain and so much of my psychological distress gets processed in my gut. Stress makes my actual physical problems so much worse.

With that said, years ago doctors told my mom she was just having stress when in fact she had colon cancer and nearly died. Keep getting tests and I hope they find something which can actually be fixed. Good luck.
