I feel you!
Me and my parents have been fighting all the time. I'm used to living on my own at college, and they are used to not having me around and having the house to themselves (I'm the youngest and my older brothers are out of the house)
So ever since I came home for summer vacation, me and my parents have been fighting non-stop. I'm ready for a vacation. Luckily, I'm going to the shore with my friends and BF this Saturday for the day. And then in mid-August, I'm going to WDW with my brother, his wife, and his wife's twin sister. Then my parents are joining us a few days later. So I'll have some time away from them.
Hang in there, OP! Maybe go for walks everyday and use that as your escape and you own time. I do that sometimes. It really helps.
