Nova... Really?

I'm tired of a lot of things right now and most of it, unfortunately, happens to be the people I'm around. If there's anyone I want to talk to about how they've been acting, it's Nova. I mean, nearly every day since middle school she's never had lunch money and gets food by mooching off of other people or being pissy about everything and to everyone until somebody buys her something just to shut her up. I don't know what to do. Like today, she hardly even talked to anyone and sat down looking pissed the whole lunch period, making it awkward, as it usually is due to something about her, whether it's her boyfriend, or her family, or acting class, or someone pissed her off, or her parents pissed her off. Anything. Something is always wrong with Nova. I stayed a little longer at lunch to get chicken nuggets and she got pissed off at me because she didn't eat. "I seriously hate you right now, like, I'm raging at you right now." Which is Nova's language for 'Hey can I have some?'. She uses reverse psychology for everything, I fucking swear. It doesn't work on me, though. I've known her since middle school, what does she expect? I mean, fucks sake, she still owes me 6 dollars from shopping in July and 8 dollars from all those times I bought her lunch in middle school, she has no right getting pissed off at me over that. And the only reason I stayed after during lunch was to get chicken nuggets because during my lunch they ran out, and when I went to the table and said "Damn it, I really wanted those, I always have those on mondays" she responded with a pissy "well at least you have food! I don't have food!" It's like this all the time. She practically makes people feel bad for even eating in front of her, like what the actual fuck. Most days there's something going wrong in my life too, sometimes I don't have lunch money, but I don't sit around and look depressed and/ or throw tantrums about it. I wish she'd grow up, because I don't think she realizes how nearly everyone at the table is seriously sick of all the shit that she dumps on us every single day. 

Ps: If there's anything else that pisses me off about this, it's that literally every day Carrie is the reason Nova doesn't go hungry, and I wish Carrie could see how much Nova uses her, it's sad. I don't even think Nova even cares for her anymore. If she didn't pay for her lunch all the damn time, I don't even think Nova would want her around.
