Help! Too much milk😰

Helpp😩😰 I just had my baby a week ago and was originally planning on formula feeding but she had other plans. Formula was not working with her stomach what so ever so I had no choice but to breastfeed. My problem is I am producing so much milk that I don’t know what to do with it all. She eats every 3-3 1/2 hours but only for like 5-10 min tops because I have so much milk she gets full so quick😩 but then I’m left with full boobs still😣 Ive had no choice but to pump them throughout the day because I get so engorged but that just makes my boobs produce more. What do I do!? How do I regulate or decrease my supply so that I’m not so rock hard and tender all the time😖 I feel so stuck.
