Where to go for Pink Eye?

Today I woke up with pink eye. Im 14 and have only got it as a little baby. My doctors office is closed on sundays, will be closed for 4th of July, and for a while after. I have absolutly no idea where to go. My eye is swollen so it looks tiny, the discharge is green, and it feels dry. Its only the right eye. I have absolutely no idea of where to go so does anyone know if a hospital will give me a prescription or not. Where else could i go. Please help! :(
