I've been fighting with my sister a lot over simple and also major things recently. She's is 22 and i'm 17

I have on many occasions yelled at her and gotten into pretty nasty fights. One such fight was when she wouldn't move her car so I could go meet a friend (the minivan I drive was blocked in by her car), and I had asked her to do so over an hour in advance, and she proceeded to cry saying she was upset and didn't feel like she could. During the end of the argument I did yell "I feel like I've never had a real sister, you've never been a sister to me." because that was the truth, and I have felt like that for a long time. I've always been ignored by her and basically grew up on my own while my other two sister excluded me from everything. I wont lie I did have anger issues and say some shitty things as a kid but grew out of it over time. I don't feel bad for saying that, because i feel like she needed to hear it. For more context this has been a recurring problem over time where she won't listen to me when I politely ask for simple tasks, and still to this day pretty much ignores me. I don't think I will ever have a good relationship with her when I eventually go off and graduate from college.

AITA for saying she doesn't feel like a sister and wanting her to know that she ruined our relationship?
