Go do a very small poo. That always helps.
In all seriousness I've been in a lot of similar situations before on the crush thing. All three girls I've liked in the past have one way or another found a way to stop being single. You want to know the worst part? They were all picked up by the same guy. He's an okay friend, but I swear he's doing it on purpose.
I'm badly organized, too. It's part of my personality. But if there's one thing I learnt, it's that you'll always get by as long as you have the heart to go on. There will not be one time when you do not eventually get off your ass and do the work you're given as long as you understand how important this stuff is.
Before you whore about a situation on the internet, think about how much worse off other people elsewhere might be. Thurthermore, (lookatmeusingthesebigboywords) think about whether posting about it on an internet forum might make it better. Specifically, this internet forum. Because beleive it or not but we're all teenagers too and most of us go through the same bullstuff.
