I think my mom is starting to resent me

(I am F 17) recently my father passed away (a month ago) and it’s been hard on everyone, and shortly after his death my mom found out he had been cheating on her with various women for 20+ years (they were married for 30 yrs) Recently when I do certain things that I don’t mean too (be a little too loud late at night or be overall forgetful and mind wondering because I have adhd) she will compare me to my dad with a look of distain in her eyes. She hasn’t done this with any of my other siblings (2 older sisters that live both in 20s) and she will be harsher on me also because my grieving process has taken much faster than theirs so I’m kinda singled out. Sometimes I haven’t even done anything wrong and she will look at me and sigh heavily shaking her head at me then walk away. I don’t know what to do because at times I feel like I don’t even want to be in my own home due to this behavior but I don’t have many places to go. I have a year until I move for college…..any advice?
