Yup... same here, random things still trigger me... sometimes after having gone weeks of being absolutely fine. Pretty sure its normal - definately healthy too, means our feelings aren't being bottled.
I'm giving 'surprised, raised eyebrows' while reading about the people who gave you 'surprised, raised eyebrows'!!! Guess it shows that you really never understand another persons journey until you've walked in their shoes... sure they just haven't experienced the same...
Will remember not to go see the movie anyway...
Take care x
