Does anyone else have coordination issues?

I am 19 done karate for 11 years now I am a ni dan and am as uncoordinated as can be- nobody believes me when I say it. Its the same in other activities that require coordination, Sometimes it amazes me that I can walk and chew gum at the same time-LOL. I have had to work extremely hard to get where I am.I always feel like a fool when we are trying to work on something advanced during cl I know exactly what to do, how to do it, I can explain it but I just don't know how to make my body move in the way I want and often mess up on basic techniques which I know how to do. Same thing when I learn a new move I just can't do it everyone else is able to do a pable first attempt as in its is an effective technique but needs to be refined while I will have this horribly sh*tty looking thing. I can look at a technique or a series of techniques in kata and instantly know and see what the move is doing how it would be used for self defense but then won't actually be able to do it with a partner for a long time. Learning a new kata sucks I always look like I am not trying I will struggle with the first couple of moves in a kata and not catch on till a week later that they are the same opening moves in another kata that I know. Sparring everyone tells me I have good strategy, even good combinations but I just can't move- I have been doing footwork drills just quarter stepping, half stepping, whole stepping, peeling off for years- sometimes for whole cl periods I can do the drills just fine- but am just hopeless... I pretty much learn through muscle memory its one of those things if it takes someone in my cl 1000 reps to be able to do an effective technique then it would take me 4000 reps. When we do partner drills and am paired up with a lower ranking student sometimes even a green belt they will have to help me just figure out how to get my body to move. My body can move in anyway I want I am hyper flexible and sometimes I get my body to to do things that are almost impossible. I did a kick once a couple years ago and everyone freaked out because a normal person would have blown out their knee- but still was a very effective kick and I had no damage and didn't know how exactly I made my body do that. Anyone ever have similar issues?
