Just a little bit of a vent

So I'm a beginner cosplayer and have been mainly focusing on cosplaying as my OCs. There's quite a few OCs I've promised to cosplay so I could finally join a few tags with my friends but it just hasn't worked out. My mom is unsupportive and I am in no position to get a job. Even when I ask for the smallest item that would at least bring me a little closer to another cosplay she just yells and calls me ungrateful, calling my hobby stupid and telling me to grow up. I'm tired of her acting like this when if the roles were reversed and my brother was the one asking, she would have allowed him to do this at the drop of a hat. The only reason she let me cosplay my first character was because it was for a school project and even then she did it with hesitance and called my entire project a fail. I'm just lowkey tired of her words at me lately, it's getting draining.
