I know how that feels...to be really upset when you know you shouldn't be. I'm sorry you are having such a tough day. Please talk to your doctor, maybe you could just take an antianxiety med (like Valium or Xanax) during your PMS instead of an antidepressant, since an antidepressant is contraindicated because of your history with seizures. I'm sure there is something that will help you. Don't give up.
