Postpartum depression..

Evelyn
My baby is almost a month old & I love her so much words couldn't explain. I have been so happy lately with her & my bf as a family, I love having them both. But recently my baby has been crying hysterically, screaming this piercing cry & there is nothing I can do to calm her down. I'll change her, feed her, hold her, put her in her swing & try everything. I don't know what's wrong with her & I haven't been able to sleep & I've been doing it all on my own. She has colic so I switched her formula to a hypoallergenic kind (nutramigen) & she's been better kind of but the last 3 days she's been popping green. This is the 4th formula I switched her to & it's been very stressful cause I feel bad I want her to be comfortable & do what's best for her. I just feel like I'm going crazy & I can't bond with her rn I don't want to have a nervous break down, she keeps crying & crying & then my bf talking shit to me & arguing with me all together is making me feel like I'm gonna lose it. Idk what to do ..
