Reality sinks in

Elena
FTM at 13.5 weeks, we made our announcements and bought a crib and stroller. The reality of this little baby is sinking in, and now I am overwhelmed with this sudden anxiety about whether or not I will be able to keep this kid alive once he/she arrives. Also thinking about all the irreversible changes on my body, our lives, etc. This baby is planned and I am thrilled for it, but today I am also afraid of the unknowns and the endless worries to come. Any other mommas struggling with similar anxiety? Second time moms have any words of wisdom to soothe the anxiety?
