Done breastfeeding

I’m officially calling it quits on breastfeeding. I’ve been ebf for a month now but I’m done. I’ve haven’t gone more than 2 days without getting a clogged duct and being in an insane amount of pain. I’ve done everything recommended to prevent them but nothing’s working and it’s taking a mental tool on me. Im absolutely miserable. Well my question is how do I wean off of breastfeeding to switch to formula?
