Hi Gav, it's a shock isn't it and I don't think there's a right or wrong way to feel at this stage. I'm 57 so not too dissimilar in age. My philosophy was, now I know I've got it let's get on a deal with it, there's nothing you could have done to prevent it its just unlucky.
One thing I've learnt from this forum is that everyone is so different with their recovery so don't beat yourself up if things are going slower, but celebrate your achievements along the way.
Each stage becomes the new normal for a period of time. The two week catheter period, the blood thinners, the pads etc but it all passes with time, and each no matter how small, is your own personal gold medal achievement. For example I'm 15 weeks post op and yesterday I did half a day with no pad in and was totally dry. It meant nothing to anyone else but to me that was pure joy, probably a silver medal, may go for the gold today 😂.
