Medication changes are always difficult and can cause some of these concerns, especially soon after changing while your body adjusts to the new medication.
I agree with Sannah here - if you are experiencing low moods that are causing these urges to resurface I would suggest giving your pdoc a call and letting them know. They may be able to modify your medications or suggest things that you can do until your next appointment to manage the change.
In the mean time, can you try to focus on the things that have helped in the past? Think of the reasons that you wanted to stop and what you did to get there. It is possible to get there again.
Good luck
