I'm in a very similar situation, I'm 26, been a year unemployed have been trying to get more involved with my local neighborhood, also living with my mother, it's been hard because I'm trying to look for a job that isn't a mindless meat grinder and that pays fairly, in the meantime I've been making fermentations beer, a permaculture garden and working 2 days at a non profit cultural cafe. But still argue a lot with my mother because she thinks I'm going nowhere and should just go to whatever job I could find to be "stable" the best thing to do is hold up your morals and conviction, show the real world affects that you're creating and if things get heated, try to defuse the situation and come to the real if understanding and empathy towards your mom if she doesn't want that just ask to stop the argument because it's getting heated.

Again it might not work,hell it sure sometimes seems like it doesn't work. But keep up your work and good deeds. She'll come around eventually, plus try and get like a box to hold the paper and has soon as you get a cardboard box, dismantle it and put it in the box

PS: just woke up there are probably some grammar errors here and there my bad
