Actually, as long as you use the trigger icon and apply the trigger code, you can still talk about suicide. The restrictions are that you can't talk about your exact METHODS for suicide, and you can't imply that you're about to commit it right then. If that's where you're at, better is to call a helpline. But otherwise we at PC are here to help you, and we aren't just ignoring that depression often comes with suicidal thoughts, and even intent.
I for instance am currently suicidally depressed. I probably will survive. I just don't think so a lot of the time, and PC can be one of the places I vent those feelings. You may find the people here are more able to truly empathize, as so many have gone through or are going through the same things.
