So sorry to read that you've been dealing with all of these symptoms, but wanted to say that I'm sending my very best wishes that you can get a speedy diagnosis/answer as to the cause of these symptoms, and more importantly - that the situation can be healed up quickly and easily.
Glad you're "back" because you're 100% right in that when times are stressful/tough, it's much better to enjoy the things that make you happy - not to mention the pleasant distraction, especially if you're having to wait around a bit for some answers.
I don't know enough about this stuff to offer up any kind of ideas, but it sounds like you're in good hands, and that this will get solved.
In the meantime, know that there are lots of us thinking of you, and that it'll get resolved soon. Sending along some virtual homemade chicken soup ...and here's hoping you're snuggling up at home a lot, taking good care of yourself while you get this sorted out.
