Welcome to pc! Sometimes medications can affect how we think. Some people get foggy brains on different medications. Some people are able to accept that in order to feel stable, while others find the side effects intolerable and vote to try different meds. It's really up to you to decide which path you want to take. Also, it may only be temporary. It could take a few months to adjust to a med, especially lamictal. Good luck! I hope you find peace.
