Yeah, I'm not giving up. When I was 18 years old or so, I basically figured that if I have two arms, two legs, and a brain, I can do good. Good things(making other people's lives easier somehow, or just working and donating to a charity, or long-term things like just being a good person)are things I could not do if I gave up. This keeps me going, but sometimes everything's just absurdly hard.

I guess you're right, I could probably just come back to this math later... It feels like something I should be able to to do right now, though. And yeah, I've stopped trying to get through to my sister, but it's pretty stressful just thinking about that situation.

Thanks for the responses guys. It helps to just communicate about it with somebody.
