Feeling Alone

I finally gave birth to my healthy little boy on 12/30/2016... we couldn't wait for him to be born and never did I actually think that I would feel this empty and depressed I figured I would be full of joy and happiness to have my little guy here. I was aware that it could happen but I hoped it wouldn't to me. I currently take depression medication but I don't know if it's working I feel like I could tell current pregnant mothers religiously to CHERISH every single second of being pregnant. I am heart broken to be by myself again. I understand why some people have many children. Having a child has been one of the best experiences in my life but also one of the most depressing... please if anyone is feeling depressed like me ask for help it's okay to ask for help or advice. I wish everyone the best and easy recovery and no depression.
