I live miserable

Me and my mum had a fight today, as soon as she entered the room first thing she says is : "im so disappointed in you, you could've done the dishes and clean the room" . Than we started this fight where she told me "ur always on call with *my online bff* , go outside stop staying on that phone every single minute!" i even told her out of anger while crying "Cuz with her i can talk about stuff i could never with you, and not that theyre secrets, basic stuffs" idk why she acts like this.. i also miss so much our old home.. indeed it was small, and not such good conditions but thats where i lived 6 years of my life.. when me and my mum where fighting she told me "Look i was today in a store with ur aunt and she bought so much stuff for ur cousin *female*, i wish i could too but i cant afford anything.. i saw such a nice bag, and such a nice t shirt, only if i had the money" my heart just broke in million on pieces and im still crying, i wish we would dont struggle so much with money, i wish we could just be like "yeah we need a new rug, we should buy one!" Not just "let's improvise something" .😕
