As a parent of a teenage girl diagnosed with Bipolar I as well as DID, I thought Lamictal would be a great change from Lithium and would contribute to her stability. Imagine my surprise when I saw this happening to my 17 year-old daughter; constant insomnia over the last three months; panic attacks; anxiety; and paranoia, especially at night. Finally, my daughter threw her Lamictal away, and she has been much better since. I don't think folks always are aware that anxiety can be a real side effect of this amazing mood stabilizer, and it's good to be on the look out for it when your kid is taking it. She also claimed it made her more depressed.
