I know this is an old post and I'm not sure if you're still here/paying attention, but would you consider writing out your health history (for your entire life..no detail is too small or insignificant), all of your current symptoms (again, no detail is insignificant), and everything you've tried and how whatever it was affected you?
I know this seems like a daunting task, but it's hard to help (yourself or someone else) without all of the information. I ultimately figured out quite a lot about myself, and what was wrong with me, by doing this.
If you decide to do it, and are comfortable posting it, I'm sure we'd all have more ideas/thoughts and be more able to help.
Don't give up. You will make it through this, and you will feel better and get your life back.
