While I am not too familiar with Dr. Phil as I don't watch that type of program, I'm not sure he can be trusted. I've heard of a few stories he's gotten that sound scripted for entertainment.
I've got to say that I'm disappointed in Brendan.
He's stated at least twice that he wants to receive treatment for his condition but to think that he can fulfill that by appearing on Dr. Phil tells me that either he doesn't understand what he needs or that he's only interested in milking the fan sympathy his condition is receiving.
On top of that to also be due to attend another convention after the incidents he's had at them which he claims to be regretful of is irresponsible and invalidates that regret.
@Mr Trick: No one is "kicking someone when their down" in pointing out that this might not be the right way to handle Brendan's condition. Sometimes it can't be helped when the truth is harsh and sometimes it NEEDS to be harsh to get through. That doesn't make it cruel. It more often than not is actually a gesture of truly caring.
The fault, I admit isn't all his own, however. It's clear that Brendon isn't always in his right mind and obviously his publicist isn't discouraging him from remaining on the public radar nor is anyone from his personal life seeming to have an interest in helping him which is quite sad. I do offer my sympathy that he is suffering and that it could have stemmed from his being sexually abused as a child if there is any truth and logical connection to that claim, I've been there (though I'm mentally fine and refuse to touch alcohol) but I can't condone a lot of his actions and choices, that he's made claims of regret and wanting help that he's not doing a very good job of showing that he means.
He needs to check himself or be checked into a rehabilitation facility and disappear from the radar for a while. The media attention isn't good for him right now, it's only being counterproductive.
