Bout to lose my mind!

My son is 7 weeks old and I’ve been trying to nurse him for over an hour and a half now! I’ve switched boobs I don’t know how many times! He’ll nurse great to the point where he’s not even comfort sucking anymore and as soon as I take him off and put him on my chest to burp him he’s rooting again or screaming because I took him off! When I reattach him he just comfort sucks till he falls asleep again! I know they use it as a comfort but it’s causing me to start to have an over supply.

ANY advice would be helpful!
