Hey, i'm also 16, with a 6 month old. I know how it can be sometimes. My daughter is always good , however...It's just the feeling of being left out in everything for me. I can only imagine how you feel, but you should def. Talk to your doctor, I didn't believe anyone could have postpartum depression, because babies are such a happy thing, but...I had it and it's terrible! I hope you get the help you need, and just know your not alone!
