Help!! Too much milk!

I had my 2nd baby a week and a half ago. And boy did my milk COME IN. I don't know what to do. I am not pumping (aside from the random pump for when I'm in so much pain I feel like I don't have any other choice and even then it's 5 min or less each side) I don't know why I'm making so much milk. I have to wear milk collectors under my shirt and empty them literally every 30 minutes. I drowned my little baby. She's constantly choking on the milk and gasping for air... This is what I've collected today from just the milk collectors... It's over 25 oz ☹️ please. Anyone...what can I do? I can't even leave my house because I'll either leak all over or I'll have to constantly check my collectors.
