Denise:
I, too, believe that things happen for a reason - because I've seen the evidence in my own life, which I won't bore you with here. I 'm afraid that many people simply miss the reason why things doesn't seem to work out the way they assume would be 'best' and miss the bigger picture, as it were. In your case, the reason appears to be fairly obvious.
I'm sorry your husband requires surgery for carpel tunnel but the timing does seem to be working out for you. I 'm sure Dan will be fine. My wife had similar surgery over ten years ago and except for the faint scar on her forearm, was relieved of the pain and had no post-op issues.
I trust that you'll be able to have your AN surgery by autumn, as you plan. Because no one ever contacted you, which I consider rude, you may have to become a bit more pro-active about scheduling your surgery. While it's perfectly normal to want to procrastinate where brain surgery is involved, you know that isn't wise - or practical. Increased hearing loss (and headaches) indicate the AN is (probably) growing. Not good. Don't procrastinate too long, Denise, it isn't worth it.
However, for now, continue to enjoy the summer and know that we're here for you. Meanwhile, take care of Dan and yourself and...
'don't be a stranger'.
