Breast feeding...

Okay I know people are going to look down on me but I jus wanna be safe... I drank last night and stopped at 9pm. Didn't drink much to bud lights and one shot barley even got buzzed. I need to know if I can still breast feed after a certain time or jus stick to formula? My boobs are not doing well and my pumps kinda broke so I had to squeeze with my hands today jus to get some pressure out of the way.

I cried like 5 times last night because I couldn't breast feed I messed up and done drinking :'(
