I feel like my parents hate me?

I've always felt left out in the family, like I wasn't really wanted or needed, or if I suddenly disappeared nobody would notice for a while. About 6 months ago I got caught by my dad doing some pretty bad things including drugs and alcohol(I'm 16) and lost my parents trust. My dad did buy me a car for my 16th birthday but i honestly don't like it. I think it's so ugly. I know you all think I'm ungreatful but I promise I'm very greatful. But my parents never really bought me things like clothes and things like that that I wanted. Once I got a job I had to literally buy everything that I wanted with my own money. I don't make much money at all so it's really hard. I'm always scared to ask for money cause they get mad at me. They buy my younger sister nice things. They bought her a iPhone 6s for Christmas and I have always had to buy my own phone. She is turning 16 in a few months and they are looking any really nice cars for her. Like way nicer than mine. They paid for her to go on a 1 month vacation with my cousins and she's getting to go to Washington DC and New York but I couldn't even go. I've been so stressed out because I have been looking for a new job because I hate mine and they don't seem to care. My step mom always yells at me for stupid things. Or when I joke around she gets so serious and yells at me. Can someone please give me some advice because it's really making me depressed and I feel like they hate me.

I don't think they hate you or you wouldnt be living with them

Your parents don't hate you. They are just stupid, unqualified people who turned out to be parents. My parents are the same way to me and my younger brother. Seems like some parents really have a thing for younger siblings.
You need to realize that not every child is entitled to be loved by parents. Parents love is more like a bonus when it comes to upbringing. There's no requirement they must love you and there's no requirement that you must love them back.
You need to learn to grow up not needing their acceptance/care.
When I was 14, I went through a really hard time in school and I had parents who strongly favored my brother over me. Everything my parents did was for my brother. Whenever he had any sort of problem(big or small), they would rush to his side with sympathy to help him out with everything. My parents didn't help me out with anything at all even when i really needed help. I learned at a young age that I didn't need my parents acceptance to live a fulfilled life. I can mooch off of them and then disappear after i graduate from college and never see them again. I don't care.
You don't need to be attached to your parents. You can love them but you don't need to be close and intimate and see how they react to your or how you react to them.
Its harder for you to do this right now cuz you're still very very reliant on your parents. But trust me: as you get older, your parents will seem increasingly less significant to you as the less you need them.
It will get easier as you get older.
Trust me if your parents hated you, they wouldn't have gotten you any car.
