Why do i hate my parents so much?

Basically over the last 3 months I've began to despise them especially my mum! She makes me so angry all the time, I try and avoid talking to her because I hater he that much and when she talks to me I walk away, I swear at them both all the time because they annoy me and make me so angry. I'm a bit upset because I feel like I'm drifting apart from them but they don't understand what I'm going through. I've started drinking a lot with my friends and smokin a lotttt of pot to try and forget about my troubles at home
