I hurt my back trying to work out yesterday (son of a bitch)

I can barely move, and i have no ibuprofen or anything here.

I also need food, and because i'm gonna have to walk my ass to the same store either way I'd like to handle both things if possible, but i'm totally broke as shit.

if you can help, it would mean a lot. I have about $3 in total between my card and change, and that's not enough to get anything.

edit: thank you!!!! this community is very kind.
