It is time for you to transfer - or get out of the house in some other way. It’s time.
This is so similar to my own situation with my mother when I was 19 and still commuting to a local university (except my mother never physically hit me.) She was verbally abusive though, and over the smallest of infractions.
The final straw was the summer after my freshman year of college, she grounded me because I stayed out with friends until three in the morning. I was 19. I started looking into transferring after that. There were other factors, too - financial ones, I was attending a private college and transferred to a state school - but the driving factor was I just couldn’t live at home with my mother anymore.
Looking back, (and she and I get along great now, but we also live six hours away from each other…) I realize she had her own issues… but neither she, nor your dad now, have an excuse for being abusive.
It also sounds like, on top of your own depression, you are doing little things to assert your independence - because really, you are still at home and being treated like a high-schooler or worse…
Please find a way to transfer to a school where it will not be possible for you to commute.
Either that, or find a way to move out of the house.
I will tell you that, as soon as I transferred to a university two hours away, my mother and I suddenly got along so much better. Even when I came home for the summer and breaks. Honestly, I think we both had our issues and we just constantly butted heads at home and were sick of each other.
And I should add that, now, 25 years later, we get along so well that we take a vacation together every year.
Distance and time apart may heal some wounds. But if not, then you especially need to get away.
Best of luck to you.
(and PS, walking the dog may have actually helped with your mood, even in the cold. Next time, force yourself to take the walk!)
