Hi Cheryl,
I followed the early days of your quit with interest. I know you've got humour and survival instincts in spades! These will help you through this no matter what it is.
Also know that you have already done the very best thing you could do for this situation when you quit -- Wow! almost 2 years! I am thrilled that you are still hanging on tightly to your quit! Give yourself a big hug today for that. Maybe you've forgotten info like the thread above. You've given yourself a better chance at whatever healing needs to happen now.
The only other thing I might recommend is what we used to make it through those early days. Remember one day at a time and breathing deeply, etc.? They're also great tools for this type of thing to keep you sane and manage the worry. You're in my prayers now Cheryl. If / when you get a chance, let us know how things go.
