Anything that involves suicidal thoughts is a crisis for me. I don't necessarily cry or emote in other ways. I usually still go to work and act like a normal person. But the visuals are constantly in my head, preventing me from thinking straight.

Suicide is pretty much the only sign I have that tells me I'm depressed. I don't have the physical symptoms for some reason, except for appetite changes. And my emotions are normally quite flat, so they are kind of useless as an indicator. But as soon as my thoughts become violent and destructive, I know I need to call someone.
