Say you know someone who thinks that they may or may not have issues should you Tell that person that he or she may have some issues or keep it a secret ??
I'd tell them. Why not. Chances are they should hear it. If this person is you than at least by posting this you have shown that you're aware you may have issues. That's good.
Depends if he is gonna make you wake up with a knife in your throat or not otherwise tell them.. I got some issues honestly.. Who doesn't though?
What if he doesn't want to admit that he has issues? Well, many people don't. If he doesn't want to admit it he doesn't have to. However the severity of his issues could be cause for concern. If he doesn't want to admit it but is displaying disturbing behaviour then someone should know. Otherwise I would confront him on it. Then if he is still really reluctant to admit it, I'd just be a good friend, unless he's really bad. In which case I'd let his family know. Internet forums are good places for admitting one's faults as the element of judgement is decreased. One has more anonymity.
