You're being criticised because you continue to back pedal every time someone says something to contradict you.
Telling us that you can't lead her because she drags you around... then when you're told this is NOT respectful behaviour, you say it's only happened once.
Telling us you can't bathe her because she's now terrified of water... then when you are told that this is not good ground manners, you say it's only happened once.
So what is it? Is your mare perfect in every way possible on the ground, never moves into your space, will move away from any pressure you put on her, will stand quietly and not move a muscle while tied, will happily stand to be bathed and will lead like a puppy dog on a long rope and stop the second you stop, turn the second you turn and walk the second you walk, always next to your shoulder and not barging in on your or dragging you anywhere.
Does she have not so great ground manners that need work? Because from what you've said, and I'm going from original posts by you not the ones that you have tried to back pedal in, that you are far from experienced and this horse has pulled the wool over your eyes. You need an experienced trainer before your mare decides its had enough of this kid that is starting to really irritate her, and turns around to have a go at you.
Don't get yourself injured or killed. Horses are big, strong animals that are not to be messed with.
