Chemistry Exam

So I've got a chemistry exam tomorrow morning and I was planning on studying this afternoon and going to bed early (I have to wake up at 5am to get ready for a string of classes). Also I have some homework for other classes to accomplish as well. It's not that I can't do it all tonight. It's just that my mom doesn't know how to get money out of the atm machine and I was originally going to go out and buy dinner. Now all of a sudden she wants to go out (she's a slow driver) and learn how to do it, on the night where I have a few hours left to do all of this shit and on top of it I have to wait an hour for her to get ready. I have to go out with her and sit beside her and teach her; on the one night where this could really wait. Now having to take care of a sick mom who can't take care of herself might sound honorable to most people, but most people don't realize that she can literally drive me up the wall with these things. Like for example when I was younger I could never bring a girl home (my name is on the lease), because if my mom doesn't like someone I bring home; she'll irritate my date and she'll make my life hell afterwards. Also even when I was kid, I could never bring friends home, since my mom liked to dress in her bathrobe or some old clothes with holes in them. Right now everything feels like shit. If everything sounds confusing it is, but after you know everything you'll understand.
