Having a hard time being happy

I found out almost a month ago that I was pregnant. I had lost almost 20 pounds and was feeling good. I was nervous about the pregnancy because I am still overweight just barley in the obese category but ever since I started going to the doctors I haven't been excited. I feel like this is going to be the longest 9 months ever. I am already testing my blood sugar and I am scheduled with a perientologist next Friday. I am frustrated because I feel like my doctor says I have nothing to worry about but then I go and see all of these other specialist. My nutritionist said there is no way I won't be put in insulin. I just want someone on my medical team to be excited for me and not make me worry about the babies development. I can't even concentrate on work right now. I just want to go home and cry.
