RAGE and anger a sign of PPD?

Heather

I’ve found that a month after giving birth I’ve become so angry and sensitive all the time. Every day I seem to find something to be angry about and it’s causing my partner and I to argue so much, putting a strain on our relationship. I feel so ugly inside for being this way and it’s so unlike me to be like this but I just don’t know why or what to do. Has anyone else experienced this???
