Is it normal to hate my sister?

For context, I’m 17F and she’s 29F. We both still live at home and she’s just so obnoxious. She constantly comes in my room to bug me, and yells at me trying to parent me. She also acts like a teenager and it’s just exhausting having to be the bigger person all the time. My dad always justifies what she does by saying “you know how she is just ignore it”. But why do I have to do the ignoring? I dread her coming home because she just storms in my room and goes through everything even when I ask her not to (she also snoops through my stuff while I’m at school). PLUS she’ll get mad at me for waking up early??? She’ll be like “why are you getting up at 5am for school what are you hiding” or yell at me for studying instead of giving her attention. I feel bad sometimes when she is nice for being so rude around her but I can’t help it. I just remember how she is and it ruins my mood.
