This will be covered up by TO's people if it is indeed true. It's shocking he would try to take his own life. He has a great deal of emotional problems, though, so his perception of reality is probably distorted.
Hope he recovers. He has had a hard life and now that he is a star I don't think he appreciates how much he has to live for, or his full measure of self-worth.
Whether it was a "natural" allergic reaction or an attempt-induced one, I hope and pray that TO recovers.
I hope the vultures around him don't cover it up. The man needs counseling and treatment. Having it be an "allergic reaction" or something like that and him not getting mental help would be the worst thing for him. I hope his real friends are there to help him get the treatment he needs.
