Comm symptoms and conditions

I have been taking Singulair for one week now due to my exercise induced asthma and allergic asthmatic symptoms. I feel very stressed out and anxious and yell at my parents a lot. Also, I feel kind of paranoid, like I feel as if somebody is watching me at all times. It is scary because I've only been on it a week. Also, my face is red and blotchy and my acne has gone from very little bumps to full blown breakouts all over. I have a barking cough and runny nose now that the doctor prescribed it. When I cough I have a pain on my left side that feels like someone is stabbing me.

I took my son off Singular a month ago, some slight improvements with the sleep and behavior problems. I voiced my concerns with my doctor twice now he looks at me like Im crazy and then he goes on the PC and says he cant find any of these side affects im talking about. My son was an appointment to see an allergist specialist.
