A bit delayed in my response :blush: but I can understand his frustration and your worry. :ghug:
S was feeling the same way over the last year, with all those varied issues he's had.... we'd barely have an answer to one question when another would come up. He was getting frustrated, upset, disheartened, etc.
I feel for C (and you)... it broke my heart when S would say it was hard and he was tired of seeing his friends out and enjoying life and he was always saying no because he felt badly or just didn't feel like going out because he was depressed about the latest symptom (or lack of answer).
I don't know how much it helped him but, when he was especially down and expecting 'nothing' from the next test or specialist, I just kept reminding him that life is long and there are periods of not so great times... sometimes they last just a few weeks but sometimes it can be much longer. And, when taken in perspective of an entire lifetime, they are just short periods... Kept reminding him that everyone has these tougher times, whether related to health or other reasons... you just have to remember they will eventually be in the past. Also reminded him that, unfortunately, getting to the final answer takes time and some turns... sometimes you simply can't avoid the time it takes to try and rule things out.
Like I said, I don't know if it helped him at all... at the time, it didn't seem to have much of a positive impact (but, you know what boys are like... a positive sign can simply be the lack of an 'eye roll'!) but... there was really nothing more I could do but try to help him be patient until the next apptmt.
I hope things start moving ahead for C!!! Thinking of you both! :ghug:
