knowing how you would kill yourself is alright-but knowing how is not the same thing as dwelling on how you would kill yourself--it really can be self destructive--negative thoughts are burrs that can get stuck in your head--
it can be frightening to think of how you would kill yourself--I don't think it is wrong, but it is cause for concern
