Cursed, I respectfully disagree with you.
If someone was to hurt themself, the idea was already there before this thread. No one just suddenly decides to hurt themself spur of the moment. It's an idea long implanted after a long time of depression, feeling alone, and wanting to finally control something in their life.
This thread is a theraputic way for people to express themselves with the security of being unknown in real life. It's similar to group therapy, except you aren't sitting in a room with the people. Yet people will still get the benefit of seeing that they are in fact not alone in the way they feel.
No one is alone in the way they feel, but people commonly think they are because it's still taboo to talk about mental illness, which is what depression is.
You are not alone. You are not "weird" for feeling this way. Depression is very very common.
