Was I wrong? I unfriended my aunt?

I unfriended my aunt on facebook. My entire life, she's always been condescending, filled with disparaging snide comments, looks down on me and her other nieces, however with my parents and her siblings she's nice. She's just sooo nasty in attitude. I literally cannot think of one time in my entire life where I enjoyed being in her presence. I just spent the weekend with her because I was accompanying my parents to the Dr. in the city where she lived, and we stayed at her house. She says things like, "you're not that deep", when I was asleep on the couch, where I was told to sleep, she'd come in at 6am, cut on the lights and blast the tv loud. She'd never treat other guests that way. To me it was her way of saying, I don't give a flip about you. I wanted to go church, I like going, and she says, "you know you don't HAVE to go" in a really snotty way." I was in a lot of back pain, and she'd say let's go walk on the harbor, knowing I couldn't go. She'd ask others if they wanted anything to eat, wouldn't ask me. But she's remember to ask me to take out the trash, or do some task around the house for her. (Which I did by the way without complaint). If others around are complimenting me for a dish I made, she definitely will not join in the compliment. But she for sure would join to complain if it didn't turn out. I just think that she's sooo rude! She's been like this my entire life. My parents love her and absolutely love having her around, but I sure don't like her. To me, I feel like she's a relative and definitely not family to me. So basically I unfriended her. I don't like her, and always feel the worse and irritated from being in her presence. But was I wrong for removing her from my friend list? I know my family will think so, but what do you think?
