Help!

So I’m 20 years old and I just had a baby on October 13th 2018. I had an easy delivery and a hard post delivery due to major swelling and blood loss. My bf was with me every step of the way and is great. Now we are home and life is hitting me hard. I don’t know why I feel this way. I feel lazy unimportant unhappy sad. Just every bad emotion you can feel. I cry for no reason sometimes and I just feel so unhappy with my life and wish things could be different. I don’t know if I should say something. Could this be ppd or just regular emotions after baby ??
