Sounds like it's time to revisit your psychiatrist and speak about your recent changes. No these are not normal, especially when you are feeling them in "incredible bouts of anger, almost rage."

With your current diagnosis, and changes at work, it may be a good idea to ease up a bit on yourself and try not to go above and beyond your duties. It seems this is just adding stress to your already fight-flight responses you have built in because of anxiety and panic disorders.

Your psychiatrist can adjust your meds to control these bursts in your mood. Until then, I'd suggest giving yourself as much of a break as you can - relaxing, doing job as expected, exercising to relieve built up stress and lots of good sleep.
