I feel like I have uncontrollable Anxiety and My parents aren't helping

I (24F) am getting ready to off to college and live in a dorm apartment. I am super super happy about being out of my parents house. But right now I have so many anxious thoughts about my application going wrong (even though it didn't) I keep doing that thing where I am constantly checking to make sure it still says I'm good and that my room reservation is ready. I try to talk to my dad about it but he just doesn't want to hear it and my mom, sweet Jesus Christ, my mom is a fucking nightmare. Her trip to see my sister and my niece was canceled because one of the in-laws got covid and it turned out to be a false positive. She didn't get her refund of the plane tickets and now she's screaming at the dogs when they follow her around and she's in a pissy mood because she is stuck with me and my dad for the week. This covid shit is driving me nuts and I am tired of staying inside. I want to go out but if I do my parents "well wait, wait..." I'm so tired of being scared I'll bring something home and I am tired of being pushed to the side simply because they don't want to deal with how I am feeling. I just want to be told everything is fine, not "Don't talk about that around mom!", "What do you mean you need this and this?" I'm just so tired of being anxious and so tired of being pushed aside. Look I know this is so dumb compared to the other problems on this page, I just wanted to vent.
