It'll get better. You wife has recovered, your surgery will go well, you'll rest post op and get back on a bike feeling so glad to be riding again!
I've got a great understanding of what you're going through, last year stopped riding in Feb because of just generally feeling none stop shitty, eventually got diagnosed with a brain tumour in June, had surgery, got back on the bike gently in September, had repeat scan in december, tumour had recurred, more surgery in January this year, just finishing 6 weeks radiotherapy now, hope to be back on the bike gently in a couple of weeks time (again).
SteveD, hope all goes well mate, world of difference between an old ugly fücker like me and a little tot and how people cope & react. Agree with your tips on surviving time off the bike as well!
