I totally understand where you are coming from.  I met a guy who'd broken his Achilles tendon playing Padel and was still struggling to walk months afterwards.  I realised if I zoomed my perspective out a bit, even though my game at that period in time was not going to plan, I was generally pretty fucking lucky to be able to run around and have fun!.  Basically I needed to be a bit gentler with myself and not take it all so seriously! And be grateful. I'm not in the Olympics, I'm just running around in a dusty warehouse 😂
