HELP 😪

I am 21 years old. I live with my mom because my parents got divorced and I don’t speak to my dad because he’s really mean. My mom and I are close but I’ve noticed that she has poor communication skills. At least with me. Yesterday I woke up super early to make her breakfast and watched some tv since we can’t go anywhere. I’ve been studying abroad for a year and I’ve just returned home. I’ve been asking my mom if I could redo my room but she wants our neighbor to do it. Last week I asked her if I could paint it myself because I’ve done it before and I’m good at it. She said no and that she wants the neighbor to do it. Yesterday on Mother’s Day I decided in the afternoon to kinda do a head start and go to the garage and some putty to fill the holes in my wall. I didn’t find everything I needed but I came back with just measuring tape. My mom saw it in my hands and started yelling like crazy and getting so angry, she was so rude to me. I went upstairs and cried my eyes out. The reason why I desperately want to o my own room is because even though my dad Is mean and doesn’t talkto me, he does house remodeling and always painted my room whatever colors I wanted as a kid. Now he can’t and I miss him and I’d like to do it myself. It’ll mean more to me. I told her that but anytime I speak she says over and over “I don’t want to argue with you” “whatever” or “okay”. A ?BILLION TIMES. That’s not effective. Then from the evening on she gave me the silent treatment or I guess we both just didn’t talk. This morning I woke up and I didn’t say anything because I didn’t know if she was ready to talk yet since I was the one to say something last and that didn’t go well. And just now she was in the bathroom and I had to pee and she says “youre gonna do the silent treatment now huh?” And I was so confused I told her how I felt again and she said I ruined Mother’s Day and I make everything about me and everything I said she yelled at me. She was mad that I didn’t greet her this morning. And she couldn’t stop talking about that. She didn’t own up to anything and just victimizers herself. It was frustrating. I just want to know if I’m wrong. I wish I had people to talk to about this but I don’t. Any suggestion on what I should do?
