Statterra Suicide

I have recently began to worry about this possibility for my son. He is on Straterra. I know all RX ADHD meds have this side effect. He has been on the med for 2 years now and I think it helps a lot. It does't cause him to be a zombie becaude it is not a stimulant. It does bother his stomach though. It does not cure all of his ADHD symptoms such as impulsiveness, and disrespect, but I beleive it makes all of his symptoms at leaste milder. He is in 5th grade now and the work is getting harder,there are higher expectations from the teacher and other staff, and his desire to fit in has increased. The other day when he was just having a bad day he stated "why do I even have a life". He has also said I wish I were never born, I wish I were dead. He doesn't frequently say these things, only on occasion. I know I have said these things my self as a child as have others by intentions of it coming true. But with the increased risk of taking ADHD meds, having ADHD, being impulsive, and the added social rejection, I WORRY! I am scared, I have considered just taking him of the meds. If the teachers wouldn't harrass me and would work w/ my son rather against him I would never have put him on meds to begin with. I  have my ways of dealing w/ him at home, its the stupid schools that might as well have forced me to put him on meds. Please share your experiences you may have in dealing w/ suicidal thoughts or your children exibiting them, also the teachers not working w/ your ids and their ADHD.
