Yall help me

I seriously love my mom but bro it's too much, she's been giving away clothes, money and other stuff to people in need, I get it like you have every right but not when your bank account is in the negatives, you're struggling to pay bills, your car still needs to be fixed because half the doors are stuck but still wanna give 20-50 DT which I think is like 10-20 dollar bills to strangers, once? I get it, twice? The max, but every week she gives away money to atleast 3 strangers and then ends up not having enough to buy groceries, I've literally been giving her my allowance and money ive been saving up from dad without telling her, wanting to support her a bit but she keeps spending it or giving it away, not to even mention that we've gotten in multiple fights cz I wake up to find her packing some of my clothes to give away, like?? She's been giving me money for me to hide for her lately so when she needs it i can give her some, my family is angry at me for not giving her money when she asks for some to give to the random people coming to our house everyday, waiting for clothes and money that she promised, I'm so scared that I'll wake up and find half my clothes gone??? What do I do no matter how much I try to knock some sense into her, she just nods and ignores me
