I have something similar but my mind seems to focus on the negative news stories... Like when I didn't know I had a concussion yet and my anxiety was at its worst, which made me depressed because I thought I was like dying or something.. But when I was looking at my Facebook feed...I see "Robin Williams commits suicide" like that came at the worst time for me so now when ever I see a movie of his at the store or someone mentions him on TV its a instant depressed mood because now whenever I think of him I think "depression and suicide"..I have learned to deal with it though like I can brush it off but for a while it was bad.
