It's worth pointing out that in some cases I think you can question causality. If a person is unbalanced enough that they could commit a horrible act like that, there is a decent chance that they have already been seen by a mental health care professional and are on drugs. With that being said I do not at all deny that these drugs very obviously and very dramatically affect a person's state of mind. This really bothered me:
Kara Jaye Anne Fuller-Otter, age 12, was on Paxil when she hung herself from a hook in her closet.
Kara’s parents said “…. the damn doctor wouldn’t take her off it and I asked him to when we went in on the second visit. I told him I thought she was having some sort of reaction to Paxil…”
It's your child. You should know your child better than the doctor does. If you need help, therapy is available for you and your child so that you can understand each other and build a strong relationship. There is no magic bullet. There is no wonder pill. Do the ****ing work. Be a parent.
