Hi Tinyrabbit,
I'm sorry you were triggered by a thread and hope you are feeling better now. Usually threads about things like suicide have trigger warnings in the form of the trigger icon

which is true in the case of the thread you mentioned. If you haven't read it already you might want to read this thread
http://forums.psychcentral.com/new-m...ease-read.html which explains about the use of the icon on PC as a warning about potentially triggering material
