Would I be wrong for leaving ?

My mom wanted my child& I to come live with her for company, I am the youngest, she’s older 77 and we have not had the best relationship but I love her& didn’t want her to be alone at this age. Well time here has been horrible. I can’t do anything like i’m a kid, I get talked down on, complained about to my siblings, if my 4 year old does anything , even simply talk with her(bc he loves her so much) she says he is stressing her out & she doesn’t walk to talk , which is her right 100% but I don’t stay around her for his feelings to be hurt, I go take him elsewhere or we stay in our room. I am doing a lot but she still complains to my siblings that it’s not enough.(She loves them ,they help with nothing really except once in awhile) I wanted a little staycation with my child& she threatened me not to leave& spend unnecessary money. (They try to watch my money & activities now that i’m here like it all belongs to her) I gave it time been here since June1, I am starting to get resentful again, because she was mean/toxic to me is why I moved away from here before, but I feel bad bc she went through a lot growing up, she taught me nothing but always criticize, not even how to drive etc. (I learned a few years ago) I feel like i’ll never be good enough for this family but she doesn’t want a caretaker coming over. Would you just leave??
