my mom took over $600 from me 😡

So I've been trying to save up money to move out because my mom practically kicked me out. I have a child's bank account right now so my mom has access to it. Today I just looked st my bank account to see she took out $615 from my savings account. I texted her & asked her about it & she said that she needed it for bill & groceries & so I got into her about not even telling me about her. She replied with "I knew you'd get mad so I didn't tell you" like wtf? I look at my account all the time. I get she needs to pay bills but she doesn't even have a fucking job. I'm soooo pissed. She said she'll pay me back but she doesn't hardly get enough to pay bills (through SS Benefits).  I've been meaning to open my own bank account but I'm looking for a national one because I'm planned on moving out of state etc etc. I'm just so upset. I was supposed to be using that money to pay off my student loans & for a place to live. She didn't even ask or tell me. I had to see it for myself which is what pisses me off the most. I'm tired of her not working because she's so damn picky about every place. "I don't want to work with money I'm bad at counting" "I don't want to drive more than 20 minutes otherwise it's too far." "I don't want to work that late. I want to be home by 3." 😩😩😡😡 she says im immature, not responsible, going to be a "stoner who can't hold a job", or I'm ruining my life but yet im the only one with a job in the family & can get good grades 🙄 & who seem to be at least kind of with their shit together. Ok I'm done sorry I had to rant
