honestly a lot of people who are serious hide it... Im pretty open about this so dont get weirded out when i was suicidal (like i was ready i had a next day mail ready to send to get to me), no one knew or would of guess it. I can only assume its the same thing, some people just fucking snap. cause you can snap into two different personalities. I have the feeling it is the same case. i mean im not violent person, in fact i broken up more fights then ever been in... most never tried to get into it with me. like the only reason i bring this up, is that there is some underlaying disorder that caused it, i would like to know know what pills he was on. That is what people should be asking for a toxicology report, i bet you'll find ssri's in his system all of them god bless
