Should I move out?

Ever since I can remember my weight has been something huge for me . I am the oldest out of 3 siblings and I come from an hispanic family. My mom ever since i was around 13-15 she always tried to make me eat healthier or restricted stuff from me or called me horrible names and just stuff about my looks and weight and keep in mind out of all my siblings she picks on me because i am the CHUBBY one. During school like high school etc she wouldn’t give me that much freedom to go to school dances or activities etc and I didn’t get to do much. My mother idk she has always been a VERYYYY clean person to the point that any little thing we do is considered dirty for her and she starts calling all of us names and getting mad for something as simple as dropping a chip. With time my siblings and i started noticing this behavior and we have grown distant with my mom because she doesn’t see what she does hurts us. I went into depression for months because of these things that were happening she always made me feel ugly in whatever i wore and said i would look way better if i looked like my cousin or this girl etc. NOWWW my grandma ( my moms mom) passed away a year ago and my mom has been super sad and it has even made her even more mean she yells at us for random stuff that shouldn’t be a big deal. We have never really celebrated birthdays or done gifts or Christmas nothing like that and I try to do it for them yk? And my parents rarely ever do it back and if they get me something they just give me their debit card and just go buy my gift myself. For my mom she says i never help or that she gives me everything and i am ungrateful and its gotten to the point where being home doesn’t feel like home at times and I just want to know if its a good idea to move out to give myself my own identity and self freedom. I cant cook or wear something as simple as a shirt cause my mom judges everything and doesn’t let me be myself. I say im fine with my weight and that i am pretty and she laughs so im just over it. I love my mom but i just have to get out of here.
