Feeling depressed

Is there any first time mummies who tried so hard to get pregnant and when you finally do, you feel so depressed, so scared that baby is going to be born unhealthy as I am obese. I am also facing rather bad morning sickness and just got diagnosed with high blood pressure at only week 8 of pregnancy, mood swings are really bad. I feel guilty for feeling like this and I don’t know how to continue on with the pregnancy #advicemommies #firsttimemom
