Devestated symptoms and conditions

We've been searching and wondering for the last 4 1/2 years what happened that November night that our 15 year old son suddenly took his own life. This boy was a fun, loving, jokester that was loved by everyone he came in contact with. We always had a stream of kids in and out of our home. He had just gotten his drivers license, went to homecoming and played on the football team.
Andrew had been on Singulair for about 3 years. He would get the stomach aches, leg cramping, odd sleeping habits and moodiness at times, but we attributed it to a young boy going through puberty. He also experienced the shakes which we were told were from the inhaler.
We had no dramatic warning signs nor was there a note. It all happened so fast that evening. He walked out of the house and 10 minutes later he was gone. Our whole community was in disbelief and devastated.
After speaking with Miller's and reading many, many testimonies on numerous sites, We feel we may have our answer to our years of wondering.

My 7 year old, active and happy, son began taking this drug in January 2007 and hasn't been the same since. He had the following side effects: fever(nonstop unless on Motrin), diarreah, depression, rashes, nightmares, hallucinations and uncountable days missed at school. We thought it was a virus or flu and even had bloodwork done to see if it was something much more serious. When asked by our family doctor about why he was so sad he didn't know why, and when asked if he ever wished he was dead he responded with "yes sometimes". We were devestated and had not researched this drug until today. We took him off the Singulair on our asthma "specialist" advice to see if this would stop the fever and instead it stopped all the symptoms. Two days ago we started it again to be sure this was what was wrong and almost immediatly we had the same symptoms as described above. I will NEVER give this drug to my son and tell every parent I can not to either. This could have taken our childs life due to poor research on our part and doctors not making us aware, even when we were crying out for help, when they prescribe these lethal drugs. Any parent who reads this please monitor your childs behavior if you choose to give them this or any drug that you are not familiar with. I'm grateful for websites like this that help us understand and see what some modern medicine is capable of. Thank you to everyone who sent their side effects in it may have saved my childs life.

I went to the doctor because I had cracked a couple of ribs. He injected me with Kenalog without advising me of any adverse reactions. I now have a golf ball size crater on my back. I'm devestated. Has anyone had any luck with lawsuits?
