Always Worrying

Ashley
I'm 24 weeks today and always worried :(. How do you all deal with it?  I feel my baby kick or hear the heartbeat and my worry subsides for a little while but then I worry again very shortly after.
I am constantly scared that something is wrong, especially if I go a bit without feeling any movement.  I just lay there trying to feel him move and most of the time he moves eventually but then I worry that the movements aren't as prominent as thy were before, like softer.  Then I think that maybe I'm getting used to it/it's in my head.  
I just can't shake the worry that something horrible is going to happen.  And googling does not help :(
