Can someone explain to me what I did wrong?

I'm a horrific cook. Probably one of the worst cooks around. I have some chicken breats and decided to bread them and fry them. Sounded easy, I thought. So, I thawed the chicken , then dipped them in egg yoak, then put them in the flour/spices mixture. The problem there is that the breading became soggy and clumpy for some reason. I put oil in my skillet and had it on medium, but after a minute or so of frying the chicken, I tried to turn them over but the breading stuck to the skillet and came off my chicken. That sucked. Some other pieces of chicken only had a little breading left. Other pieces had burnt breading. Did this have something to do with my skillet losing it's non-stick coating? I put plenty of oil in the skillet and had it on medium. Can someone tell me what I did wrong? Because my chicken had almost no breading left and was bunt on the outside long before it was done on the inside. And all the oil in my skillet was gone too. I'm angry.
