Oh mate, I can sympathise and you can find support here. I absolutely understand about being upset and withdrawn. Once I get home from work, all done putting on a brave face, (because God knows they're all pretty sick of my sour face there lol) I am all out of energy and resources and my poor hubby and kids get the leftovers, which isn't much! You must feel awful, I am 35 and feel like my life is over, you must be so depressed.
I do get severe neck pain, it is my main and unmoving symptom, so I know how scary it is. I was in a bad way this last weekend, and couldn't stand it, I did break down this time, as strong as I have tried to be I couldn't handle it anymore. No one who hasn't had this can possibly understand the agony we are in. They think this is just a bit of heartburn.
I too get asthma when my acid is bad. I believe the trachea becomes irritated and that is why we wheeze, and also why the throat tightens up, to prevent acid going down the windpipe. It makes sense anyway.
Don't give up. We are strong, we can beat this!
