What is wrong with my mother?

I feel like nothing I do is right with my mother. When I'm talking she'll complain I'm swishing liquid dangerously around in my glass. Every time I come home and I've had a hard day myself she will complain I am too loud and 'too much energy for her.' I always have to watch my p's and q's around her. Then we were sleeping in different rooms taking a nap, and she tries to blame my dad's noisy movements on me and criticises the fact I choke on phlegm from my cold loudly.
