Trouble with parents

My mom most of the time says negative things about and thinks things wrong about me. She things I’m not normal and don’t have any friends and she just complains on the littlest things. For example,she says I have too much hoodies and should change style. They even complain about me wearing a hoodie during dinner time they says it’s because it is not cold in the house.That last time I ever heard her say something nice to me was when I got honor roll(good grades). I never cry not even when watching a sad movie.The only reason I cry because my parents did something to me. I really don’t want cry but it’s just so hard not to. My mom was even thinking about sending to private school just because how I act at home. At school the teachers have no problems with me but at home my parents always have a problem with. I have alot of friends. I just don’t want her to know about them. I usually keep most things to myself with my parents because everything is so embarrassing around them.
