This is the only place where I can communicate my thoughts and feelings honestly without pretending. I don't need to fear judgement because people here have experienced same kind of stuff and make an effort to listen. I can talk about suicide, death and my fears without people just going "Suicide is bad" or brushing it off.
In other words, this is the only place where I can feel authentic connection to people. I'm also pretty lonely and I like reading posts and spending time here when I'm bored.
