How are you doing today? The Lamictal takes weeks to get into your system, it is upped each week - 25mg. So, you need to give it time.
I know how that feels to cry at the drop of a hat, it is so hard to control.
Maybe your p-doc can give you something to get over the bump for anxiety until the Lamictal is at its peak, in your system
Are you on any anti-depressant????
