Is My Life Falling Apart?

So my brother didn't manage to go to school today. He's had a truancy problem, but it's been fine for the past few weeks. Today, he just couldn't get up, he was ready for school but just couldn't get out the bed. My mom decided to overreact about it and flip out. Now she's threatening to leave, so I'm stuck with my brother and useless dad. Now my brother could manage to help, but even then my dad wouldn't get a job. My mom is what I need for money and so that I don't live as a poor little fucker that has even more to complain about. So now, my brother and I are staying up to clean the house so she can calm down a little bit and quit her bitching. It's honestly starting to piss me off. She freaking says she doesn't want to screw me over or watch me get screwed over because it's not too late for me. I don't think it's too late for my brother, it's definitely too late for my dad. But she says that, and that she doesn't want me to get influenced and screwed up because of anyone in my family, I'm the best set for a good future. But then she threatens to leave, even though she hasn't thought of it she should realize how much that's going to fuck me. I'm going to have to put up with my lazy ass dad who's going to be even cheaper and then my health will deteriorate. I'm not going to be able to get all my cavities filled, still have 4. Doing weightlifting may have to stop because I won't have room for a benchpress in the apartment I'd end up moving into. My social life will get fucked even worse. To think I can't get a girlfriend now, think of what'll happen when I sweet talk one and then when I take her back to me "house" she finds out my room is one I share with my brother and my basement I call a chill pad and kind of brag about when I'm in the mood is nonexistent. It will make me look like shit.
