I am trying medication (20mg citalopram) because I am the same way (actually my father was like that) so that is sadly hereditary. I am also working more (this is the busy season) for us. Today, I called in sick as citalopram gives me occasional diarrhea. Next year I may just get a medical leave (I am turning 60 in Dec 2017) So you are not alone. I don't know what else to say except [hugs]
Unfortunately, my anti anxiety pills are not doing any miracles. Let's see maybe Jan will get better.
