What Causes Severe Anxiety And Lack Of Focus After Lamotrigine Withdrawal?

Hello! my friend has been off of Lamotrigine for a week and a half now and is having sever issues. She is not able to focus and is having serious anxiety attacks. She has not talked to her doctor yet and I don t know if I should convince her to going to the hospital for inpatient. She has remembered where she put it but I m not a doctor and don t know how many mg she should start taking again. PLEASE HELP!!!
