Postpartum confusion?

I immediately got the baby blues... My son is now 3 weeks 4 days I take 50mg Zoloft but I feel like it's not working, it did whike I was pregnant but now I feel like this postpartum depression is on some days and off others and not only is it driving me crazy but I know that the people around me are affected as well because I hear them asking "why I'm so angry all the time" I'm getting help but fuck! I want to be normal again!!

This was on a good day..
