I completely understand the relief when getting a diagnosis. Once there is a name for what we have and a plan for the future it lets you breath a little. Now there are medicines to help and doctors don't look at you like you are nuts because you have all these weird symptoms. I am happy that you are at that place now. Of course it would be best if you were not ill at all but if you have to be then at least you have a name for it.
Once again, welcome to our family. I look forward to getting to know you
