Does anyone else ever get random suicide thoughts that you know you would NEVER act on? 

For example, mine is when I'm at train or subway stations, while the train or subway is coming in I have the thought "what if I jumped in front of this?" It's there for maybe a couple seconds and then gone, I'm never worried because I wouldn't do anything, and I always find myself taking a step back as if to reassure myself I won't.

I asked my psychiatrist and he said it's normal for people who have been in crippling depressions to have these thoughts just pop back up, and my social worker even admitted when she's in tall building on a balcony, the thought of "what if I jump?" Comes to her head - so I don't feel too weird.

Anyone else?
