Thought pattern symptoms and conditions

My son, who just turned 14 this month, was on Singulair for over 2 years.
He was diagnosed with reactive airway disease and possibly Asthma--and prescribed this awful drug-even back in 2004. The doctor said how wonderful this med was and prevents any further attacks.. So, for 2 years-every night, he took this mood altering, destructive drug. He lost all interest in school, his athletics-soccer, skateboarding, biking..in fact became almost a vacant , very unhappy, child-had stomach aches, joint pains and reflux--why--I brought him to the doctor and Pediatric center so frequently--all they kept saying his --his asthma is better, much be other issues...Even after the March 2008 suicide--his doctor said-that is just an isolated incident-just monitor him--It is a good drug. Right, month by month his behavior escalated to wanting to die, no reason to go to school-he said he was stupid and a failure and why don't I understand there is no reason to his life. A usually happy fun-loving boy -my son- didn't want to live. Nothing made him happy-I started to believe what the doctors said--maybe something or someone at school (bully, pedophile??) caused this change. Terrible nightmares and vivid dreams...Until this past July, I asked him want to go to the library for some books or dvd's...he went ballistic-threw everything off his computer desk and tried to break his chair. He is not an aggressive boy but this behavior was becoming a daily issue. Along with everything flying off his table, was his bottle of Singulair pills. It then dawned on me..I have been poisoning my only son. The child I know and love and gave birth to returned within a few days--although I am worried sick about further asthma attacks --all the doctors can prescribe is a steroid drug-asthmex or Pulmicort.. I cannot understand nor comprehend why this drug is being prescribed for children and young adults. The guilt I live with is terrible as my son has lost 2 years of his life--
and thought there was something really wrong with him-At least we woke up---in time--how about some other parents..thinking it's just normal adolescent behavior for their child or their fault???

I have been back on 125mg of Top for about 9 months now. I tried it for 1 year prior to this with too many side effect. I have taken it for migraines and an eating disorder. Instead of helping this time around I believe it triggered emotional issues, panic attacks, nerve damage in the occipital region of the left side of my brain (more than what seemed to already be causing headaches from the start), I relapsed with my eating disorder and lost too much weight, and had something called psychosis. Psychosis is a disordered thought pattern seen in many different mental illnesses or those in a confused state of mind. When I'd look at a stop like I would not be able to determine in my mind whether it was red or green and I would just go through it. I felt like I was going into some sort of coma all the time as well. Now that I am on an eating plan and exercising a bit less the side effects are a little less but the doctors are looking for an alternative at this time. I have tried every med out there.
