Postpartum depression

I have been diagnosed with ppd. I have support but still feel like a pos mother. I deliever 3 weeks early and had medical problems durning the last 2 weeks before i had to have a c section. Once my son was born he weighted 8 pounds but was send to NICU due to low blood sugar. He is almost a month old and nothing is getting better. We still go to a doctor every monday and i still break down and get angry at simple things especially when my family grabs my son. I dont know anymore...
