You can get addicted to certain emotions. I'm not sure what anyone else is addicted to, but mine is hope coupled with the relief when someone is okay. They are too short lived, however.
Unfortunately, the more common emotions for me are grief and disbelief and the need for closure.
I keep telling myself to quit this place, but I keep accidentally opening new threads. And the whole cycle starts all over. I hope my semi detached input and support has meaning to those who are suffering. It does to me.
