I have a few triggers, but I will keep them private for now. For me, I find it helpful to be triggered every now and again. I use it as a reminder of the areas I am emotionally raw and or vulnerable in. If it hurts, I generally know it is something that needs work. Outside of triggers, I do find it brings me down when individuals use hateful self talk. I do not see the value in it, but it isn't a trigger per say.
For me, the most supportive and helpful communication style is a simple and direct approach. I am not always great at reading between the lines, so I prefer it when you just tell me what's on your mind even if it is tough to hear. Of course, if that's not your way or if you prefer another style I'm willing to roll with it.
