Sorry Carrie, I didn't know it was a long term thing or I wouldn't have said sadness. Others have told me that it comes and as always life has it's ups and downs. I hope the down bit for you is short lived. Try not to be scared because fear can exacerbate it I think. (does for me anyway).
I hope you have a good night there. I was in Eire once, up and down the West coast. It's a beautiful country from what I saw.
