Please help me deal with my mother?

So my mother has always been rediculously strict since I was born...on top of that her way of parenting is wrong...when I was 3 or 4 I didn't want to eat the pizza, so she made me cry and "scared" me into eating it, while my dad just wanted to explain to me why I should eat it. My mom refused to allow my dad to help and now he won't get involved or anything. Still to this day she does the same sort of things and I wish my mom would realize that I'm not stupid and his way is better, but she won't. My mom gave me a bit more give when I got into highschool, but since I'd been horribly sheltered and was not even allowed to go to someones house for a sleepover, I got a TINY bit wild. by wild I mean barely. Like the worst thing I did was skip cl to go to my boyfriends house. He also came to our house a lot when my parents weren't home...so apparently my neighbors tattled on me and this morning my mom walks in and says stuff like I'm leaving..don't know when I'll be back, could be 20 min
