I have had this fear since I was little, one of my earliest dream memories was of seeing my parents' skeletons. I lost both my parents 4 and 6 years ago and felt like the "well the worst happened." But now one of my cats isn't doing so well and I'm a total wreck. I eat when I can, with a swig of pepto. I've been on some klonopin but I still feel the worry, the klono just stops the horrible physical anxiety like burning skin etc. It's so so hard for me not to catastrophize even though the vet says to be optimistic because her condition often just goes away.
