Stress
In terms of your work schedule, this isn't particularly a high-stress field. You make your own hours for the most part and can consult with other professionals if a case is particularly challenging.
That being said, you might find a patient is close to a breakthrough but just not quite getting there, which could be a bit taxing. You'll be able to consult others for support, but other than that you may just have to be patient. Progress in these sorts of matters can be slow-going, even painful at times. Remember to try to leave that stress at the office.
