I'm so sad to hear about all you have endured over the last few months, I really can't imagine the agony but I can imagine how totally exhausted you must be feeling. That's an awful lot to deal with emotionally and physically. I can't say that I've been through anything close but I do understand not being able to face surgery. For completely different reasons, I experienced a complete inability to cope emotionally with the thought of surgery, I cancelled my first scheduled hip replacement nearly four years ago. At the time I was being tested for Lupus, that was up in the air and inconclusive. I'd suddenly seized up completely, couldn't bend, walking was difficult and I sat down with a surgeon who said I needed all four joints replaced. It was all too much. I was told I had severe chronic arthritis and the year before I was fit and healthy. I can't say anything to take away anything that you are going through and I certainly didn't want to listen to anybody tell me to be brave and get surgery back then. All I can say with hindsight now is that I really wish I'd have had surgery sooner. I was very nervous of having surgery and as soon as I woke up, I realised that I'd gotten into a state over nothing. It was so much easier than anything I'd imagined. Those early days were not great but they were not that bad either. Despite all my continuing issues and the fact I may be a bit disabled for good. I'm so much better than I was. That last few months before I had surgery was incredibly hard. I didn't imagine my hip could get much worse but boy was I wrong. I really would have been wheelchair bound, I really should have been those last few weeks. Unfortunately, hips very often do continue to deteriorate from bad to no longer holding us up. I'm not perfect but I'm better and it's made so much difference to my life already.
As a foot note... I've been told my next surgery will not improve my mobility but I'm still keen to go ahead. Why? Because I know that although it may not fix my issues it will stop my issues getting worse. Just a thought.
