A bit scared

I'm right at 23w. Really starting to see a belly bump now, even when I'm lying down.

I was in bed the other night and suddenly started to freak out.

"Oh my gosh, this is actually happening isn't it?" "I'm gonna have a kid" "I'm never going back to being 'single' again" "I won't be able to just pack up and travel like I used to, cuz I'll have to make arrangements for the kid" "I won't be able to work late and go for drinks with coworkers anymore cuz I'll feel guilty/be guilt-tripped" "All my savings will go to taking care of the kid -- no more retail therapy for me"

I'm such a horrible mom for thinking this, but the fact that I'll have a kid for the rest of my life, and have to deal with the gigantic responsibilities for the next 18 years at the least is terrifying.

I thought I was ready to have a kid when we were ttc, but now I feel scared and horrible that I feel scared.

Has no one ever felt this way?
