im so scared

I feel like I've let everyone down.. I'm trying so hard to not take this blessing for granted... but I feel absolutely horrible. I'm crying on my birthday and I feel like complete shit. I am so terrified to give birth. I'm so terrified to announce it to the rest of my family because I will be judged for being 19 and newly married. I feel absolutely horrible and I'm crying in my car and I can't stop.... I am so so scared. I feel so alone ... please Lord help me
