Singulair Hospital Emergency Room, Anxiety Attacks, Litter Sister, Missing School, Fluoxetine

I posted last week. My 16 year old has been taking singular for 4.5 years and has been off singulair 8 days now. She was given Fluoxetine by her Psychiatrist 2 years after starting singulair. This did not help her. Her grades had droped, she was depressed all the time, missing school because of stomach pains and headach (she had to be taken to the emergency room and given medicine for this and for anxiety attacks), She had tremors of the hands and feet, so,so sad all the time. Never smiled. It was nothing we talked about to family and friends (just her Doctor, Psychiatrist, and Hospital emergency room). She even started cutting her legs with razors. 3 days off of singulair she came into the livinging room and watched a movie with us. Her little sister said that sissy is getting nicer. I have not mentioned the singulair to her litter sister. 5 days off she came and sat with me in my oversized chair and showed me a very colorful purse (not dark) that she would like to order (which I did). She has not sat beside me in four years or allowed me to touch her willingly for almost that amount of time. She has eaten diner with us the past 5 days and smiles sometimes. I love her so much and am wondering if her life path has been forever altered by this medication or will she be able to recover from all this . TKU
