For me finding the right medication/tions and a good cognitive behavioral therapist has helped. You can't control the extreme as far as I can tell, only ride then out. I am the same way when my meds aren't working. Happy, sad, angry, depressed all in a very short period of time. Geodon and Lithium have helped the most along with Prozac. Those three are what I currently take. Doc won't put me on an antianxiety medication
