Myzen, first congratulations for finding effective ways to deal with what triggers you.
As for myself, I don't know if I have any triggers on a unconsious level. I feel that I'm always aware of what triggers me. I have flashbacks quite frequently to my childhood traumas, so they are always fresh in my mind but not to the point that they will send me into a tailspin. However; I can definitely be triggered by seeing things written here, elsewhere or IRL. And what triggers one person may not trigger the next. So, marking a post as a 'trigger' can only go so far. There are perfectly mundane everyday things in life that are very real triggers for me so going into any post puts me at risk.
I've only recently started individual therapy so I haven't reached a point of effectively dealing with my triggers and actually we haven't even delved into my past yet. There seems to be too much going on in the here and now in my life to get to anything any deeper. I do realize though that the way I react to things in the here and now probably has some relationship to my past traumas and childhood and until I deal with them and can lay them to rest, if that's even possible, then I may always be reacting in a negative way to things in the here and now. Gosh, that sounded all jumbled when I typed it, hope it makes sense when you read it.
Bottom line though is that I am a baby work-in-progress when it comes to dealing with my triggers, so at this point I don't cope well at all. They usually bring on a major mood swing, as I am BP.
