Stopping cold turkey is hard on everyone
Never had this problem, but here are some ideas.
Cabbage leaves on your breasts can help you feel better, I always prefered cold packs to hot packs, so I would just put them in my bra cold. And something in them really does dry up milk slightly.
Heat increses the blood flow to the area, which will increase the milk, but should also decrease any infection. Cold will decrease the blood supply and lymph that is building up in your breast tissues to get ready for milk production, and I think it feels better!
Keep on letting them run out, but don't empty them, just express the smallest amount you think will keep you healthy.
Maybe try to keep on more shirts then normal at night so physical touches aren't encouraging milk.
Maybe make sure you are laying down sometimes when you express (not always standing in the shower) so that your breast drains a little more evenly.
If you do decide to pump for a while maybe give it to your daughter in a cup or make something with the milk so at least it is also something good in your life still not just sore leaky breasts that won't do what you want.
I don't know if any of this will help. I hope you feel better.
