I know how you feel, I am actually afraid of myself at times. The more stressed I get the more it occurs so I feel it is my brain scrambling from stress. Then for days it doesn't occur and it is a relief. The job I have is very stressful and I am looking for other employment before the stress does me in. I am tired of doubting myself and fearing what will happen next. I know the job stress is an issue as sometimes I will go work in another department and the stress there is much less, and it is a great day at work. In fact the staff comments on how rude and cruel my department's staff can be, so I know it is not just me stressing myself out. Unfortunately with this economic demise, finding another job without a long drive to work is not happening at this time.
