Unhappy baby

Ok so when I found out I was pregnant, I got so depressed and I wasnt sure I even wanted the child. I suffered from almost dailey anxiety attacks, constantly cried and worried about the future of my child and life afterwords. Now I have this wonderful little boy who is alomst 2 months old, im glad I have him and although the pregnancy was not physically had it was the worst emotional thing I have ever went through. Im still depressed and emotinal now but I feel im getting better. anyway I belive that since I suffered from ppd during my pregnancy my baby was greatly affected.. my baby NEVER smils and NEVER laughs. I have only seem him smile maybe 2 times and he was asleep both times and he laughed only once also alseep... has anyone experienced the same thing? Unhappy baby with ppd during pregnancy? My SO tells me it isnt my fault and I shouldn't dwell on it but I cant help it...
