Sometimes mood shifts are not always typical. Hypomania can often be present as rage or anxiety, not only elation. I often get "mixed episodes" where I feel an overall agitation and anxiety, not a classic depressive or hypomanic symptom. Just a thought to consider. Best wishes in your treatment! I hope you're telling your doctor how you feel about the Lithium. Doctors often prescribe more than one drug at a time to balance things out. Good luck!
