There's room in life for both biking and corner-sitting while knitting & stout drinking, lady!
Being tired really doesn't help - it's hard enough pillying when you're tired, let alone riding.
The proof of the pudding is in the riding... sitting on a bike in a shop isn't really enough of a flavour, you really do need to get out there and try riding different bikes. The different riding positions make a huge difference to the way you have to ride and the degree of comfort/discomfort you'll feel.
Try not to give up what you've worked so hard to achieve, but do find a way to make it fun and fulfilling
It's represented such huge life changes for you and it's been hard work on so many levels - I can barely begin to imagine just how much work! You've achieved amazing results and it just shows you for the gutsy individual you are... you're a very determined lady and your attitude to life's curve-balls should be blueprinted for others to aspire to!
Hang in there CG & have a boosting
to be going on with, til you find the bike with your name plastered all over it xxx
