Don't be sorry.
You're doing the best you can with what you've got, and everything is still falling apart, but calm down, take a deep breath, because it isn't your fault. You're fighting a losing battle, but guess what, if you give up now you'll never get to the end, where you find out you really won. You're struggling, you're crying and you're lagging behind. Asking yourself, maybe I can't do this. Maybe I wasn't made for this. But don't give in, don't cave. Tell yourself, you're stupid for thinking those things. And that you're actually very smart, stupidly smart even. When it begins to rain fire, it's your job to bring out the fireworks and turn it around. Yes, it's easier said than done, but you've got to start by writing it all down.
