Ppd vs hormones vs sad...UPDATE

I can't tell if I have mild postpartum or if just my horomones. Today I can't stop crying. I feel so sad and there are days we're I wonder if I should bother carrying on. Being a mum is hard but I love it and I am so in love with my boy but I don't feel myself. I'm so irritable and angry and sad and happy all at the same time. I breastfeed so I know my horomones are all over the place! I can't sleep even when my boy is alseep and then I struggle getting up! I don't know how long I can go on pretending I'm ok when I'm not. But I'm not unhappy I'm just sad if that makes sense.
I dont even know anymore
UPDATE
Been to the dr today and confirmed its ppd! Thanks for the comments xx
