Feeling Crazy

First time mom here 24 weeks along, so maybe it's all normal, but I feel so scared and nervous everyday that something bad has happened to the baby and it's no longer alive (to put it bluntly). No indications of this, just paranoid and scared. 4 weeks between appointments is agonizing.

I feel baby move, but then talk myself out of it since I can't recreate it on demand (again, crazy).

I'm super emotional today and just can't focus. Sigh. Will it ever get easier?
