Is it normal my mum calls me greedy?
So I've been saving up for about six months now for something I've really wanted, it takes me a long time just to save up a bit of money though as I cannot work due to some disabilities and rely on the government, although half of the money I receive goes to my mum to pay for food/rent/electricity/etc. and after buying my medicine, food for my pets I'm not really left with much money.
So I had saved up a couple hundred dollars and was ready to buy the thing I wanted, however my mum takes my card without my permission and goes and spends half of the money I was saving. I get angry because she didn't even ask me before doing it, and a week later she spends the rest of it without asking me again. She said she will pay me back eventually, but I'm pretty sad because I was really looking forward to buying that thing I wanted.
I decide to go and talk to her about it and that I told her I don't want her stealing my money and taking it without asking me first, she gets really defensive and then starts calling me greedy and selfish for saving up a few hundred for myself and not spending it on her. My sister then starts calling me that too cause she was there and overheard the conversation.
So am I greedy and selfish for saving up my own money to buy something for myself? Also for the people who might say to just move out, I cannot afford to move out right now until next year as that's when I will get enough money to live by myself, right now I only get very little and I could never afford to live by myself unless I become homeless. I will definitely be moving away from my mum next year
