p-ppd (postpartum depression)

Past-postpartum depression is creeping up into my mind as I quickly approach the birth of my 2nd child. 1st time around I was told breastfeeding was the way and the only way my baby could recieve the best nutrition. I developed mastitis very quickly and on top of trying to heal my bottom my top was now out of commission. I fell deep deep down the bunny hole of depression because I felt like I had failed my daughter the best life she could have. She is now 2 and one of the healthiest toddlers around and that ppd slowly went away. It is starting to come back around as now it is time to decide whether I try to breastfeed again or I do not go down that deep dark path again that I went through the first time. I am wondering if any other moms went through this? I am fully aware now that a fed baby is a happy baby but I cannot help but let those old thoughts creep into my mind as I get thousands of questions of I will try to breastfeed this time. I am torn and unsure on what to do.
