At least my swim cap is cute

I still don't like swimming. I feel watery and seasick when I drag myself out of the pool. Ugh. Not to mention the breathing issue. I'm concerned how I'm going to manage that at the race. Currently I feel like I can't get a good breath after a couple of laps. They tell us to flip on our backs until we're breathing normally again but that's not working. The only way I can get a good intake is by getting my chest out of the water. The river in Philly isn't going to be kind of to offer ledges for me to do that.

We had a stroke clinic last Thursday (not that kind of a stroke, nor that kind of a clinic). It helped to see someone who knew what she was doing show us what it's supposed to look like. I always visualize myself as I'm swimming but without a comparison it's a mute observation.
It helps, now, to "see" what I'm doing but I still don't have the body position right. I'm either arching my back too much so my rear is sticking out or I'm dragging my legs through the water.
What is the adjustment I need to make? I know it's something simple but I don't know what it is.

For now, I'll just keep drudging to the pool and working on one aspect at a time. Got any tips?
