I wanna be happy but I don't know how to.?

I've been feeling down for the past years and I wanna be happy I just don't know how to. My family makes me so stressed and pissed off. My mom and I don't get along and she says the most insulting things and it just pisses me off. Its sort of a routine my mom and her mom didn't get along and my grandmother and her mom didn't get along. Now my mom and I don't get along. Another thing I love to cook but every time i make something there's a nasty comment. Why is it like this? Is it supposed to be like this? It need more sugar or some times salt? Like what the hell? Now don't get me wrong i am sensitive but im not exaggerating. When i want to buy things so i can make something its always like your raising the grocery bill. Ok so here;s the deal everybody gets there own snacks from the grocery store my older sister gets her things my other siblings get there things. So i decided instead of getting my own snacks i would get baking things like flour, sugar etc. And let me tell you something it is the same amount of money as the snacks i would get. Now i feel bad that she always says you raise the grocery bill. You don't need to bake we do need to eat. usually i would quit and say you know what fine then no more desserts. But it something i love something i want to do i love to do. I don't want to stop so i pay for my own ingredients and sometimes i don't have the money. I don't have friends or you can call them friends but they live out of state and not where I am. I cant express my feelings to them they just shut me out. I don't drive, I barely leave the house.Its so hard to try and be happy when everyone around you is so negative and loves to put you down and make you feel bad. I'm only 16 for gods sake i don't know what to do with myself. like i'm just miserable. I try to forget the negative things such as things that were said and done but i cant they always seem to comeback. I feel like i wanna go away and crumble be by myself. Any Advice.
