DMER and Breastfeeding

I have a severe case of DMER and every time I breastfeed or pump I experience the rush of intense sadness and depressed feelings thereafter. It last for pretty much the entire time until I'm done feeding/pumping. I'm proud that I made it to 7 months mark with EBF, but starting to lose motivation here.. if you suffer from DMER, how do you deal with it? I know nothing is wrong with formula, but I just personally enjoy seeing my baby thrive on my breast milk. Encouragement/tips appreciated!
