Change your diet. Get off all the sodas and other sugary and caffeinated beverages to help with the anxiety. Exercise an hour a day. Talk to your doctor about the rest.
See endcrinologist. High testosterone may lead to rages and emotional fluctuations. However this is generally rare unless you are taking supplemental testosterone at higher than recommended doses. If you are concerned about your levels, see your internist or endocrinologist who will measure your serum concentrations and provide better answers to your questions following a thorough evaluation.
