Stopping Lexapro and Lamictal (at different times) both made me feel super wonky and messed with my mood for a bit. Well the Lexapro seriously messed me up when I came off it. I even tapered off it for a week or so and it was still bad. Doing both at once seems like a lot to go through. It also seems a bit concerning that you are feeling impulsive. I would recommend talking to your psychiatrist and therapist as well if you have one. Psychiatrist could talk about the possible reaction to withdrawing and if it is safe to be off meds, and therapist could also help by checking if you are making a rational decision when it comes to your job. I hope you feel better soon.
