I found out I lost my little step sister this weekend..I'm trying not to get all worked up and trying to stay busy or doing stuff to try and ease my mind..I am 13wks 1 day and not sure how to handle this..I'm scared because I don't want anything to happen to the baby..

No rude comments please, much appreciated in advance
