Beautiful face symptoms and conditions

My 13 year old daughter has been taking singulair for 8 months, and started suffering from severe depression 6 months ago. We intervened and prevented her from committing suicide, but barely. We never correlated it with the Singulair until a visit with her pediatrician today. I am so sad I want to cry. I am the one that suggested to her asthma specialist that she be put on Singulair. I am so fortunate her pediatrician caught this. We couldn't figure out why her personality suddenly changed.
