Here too OP. I am so clumsy and I am always full of bruises for walking into things , or falling over my own feet at times it seems. I can see something, know it's there, plan to avoid it and I'll still walk into it.
I have many of the other typical traits like lack of sense of direction, I get around that my always using maps if I am driving, or if I am walking I will mentally mark spots, like I'm a shopping mall, I will make note of what shop is near the door I need to exit from to find my car, and in a very big multistory I will take a photo of my car parking spot number and floor level. I have lost my car so many times so small things like this help me along the way.
If I attempt a gym class, I like pilates and yoga etc, then I always go to the very back and make sure someone is in front of me. As the instructor is facing us so is opposite, and in the mirror it is opposite, so I battle to follow. Yes I am that one always going to the wrong side. If I am behind someone else, I can follow them instead. I always hope no one is following me 😄
I suppose we just have to adapt and do what we need to to get by. I also have very sturdy mugs as I don't know why but i tend to drop things more so in the mornings. So coffee mugs are those chunky kind, as quite a lot of the time I misgauge putting it down on the side.
I always have arnica on hand as I find bruises all the time and half the time I have no idea from which stumble, fall, slip, bumping into things it happened from.
