I'm so happy my baby is here but feeling depressed

Cherokee
I'm so happy about my new bundle of joy born June 23, 2017 @ 7:33am.. I can't help but feel so sad and depressed, and trying to distract myself with the baby and cleaning ain't helping. I dont want to feel like this I feel like I'm letting my husband and kids down by feeling this way. I'm feeling so alone and I literally feel like I have no one to turn too!
