Mental breakdown

I'm struggling with being pregnant. I have my first baby when I was very young and I lost him when he was 3 to cancer. That was 10 years ago and I whole heartly believed i had dealt my feeling. Now I'm married and 9 weeks pregnant and all these feelings are rushing back. All the stress and anxiety. I know how excited my husband is but at the moment I don't feel mentally able to do this. I just want to be excited but I have nothing but fear.

I don't need anyone to feel sad or sorry for me. I just need to tell someone.
