Anyone able to relate?

I have an 17 month old son and I’m currently 20 weeks today. I had ppd with my son as well. I have experienced sooo many emotions this pregnancy and I can’t help but to feel a sense of guilt and fear? I feel as though I won’t be able to give both kids my attention or love, maybe I won’t be enough as a mom.I feel like my son deserved more time with just his dad and I and that he may feel like he’s pushed aside. We had wanted a second and I was so excited when I found out. I don’t understand why I feel sort of withdrawn? I was so I obsessed with my pregnancy with my son, always shopping beginning at 12 weeks. We rushed to find out the gender and I always talked to my belly. Now I will be chasing my son, lack of energy and being reminded by my growing belly or baby kicks that I am actually growing another human. I am thankful to God for blessing us with another child, I just want to fully feel that joy and happiness. Thank you all, for allowing me to vent.
