Dr. Beth, I have a problem and people keep telling me that it is bigger than I think it is.  I have lost several jobs over the years, usually due to blowing up at my boss or a coworker. I tend to get angry and irritated easily at everyone from family members to complete strangers in grocery stores and gas stations. When I get into a project or hobby, nothing can stop me. I may work non-stop for days at a time, barely sleeping and sometimes I go on online buying binges.  I find that I tend to be either really happy and have a lot of energy or down in the dumps and unmotivated to get anything done. At those times, I feel really depressed. I’m seldom “in the middle”.  My family thinks I have bipolar illness but I think I just have normal moods and typical life problems. How do I find out which of us is right?
