Thank you for your reply, JackBlack.
I am so disillushioned with it that I don't see that I help patients anymore (if I weren't there, someone else would be in my place) Of course, when I went into medicine it was to help people, but now with acute medical on calls, it seems I'm not helping them, it's just an endless conveyer belt of patients that you may order a test here and there on, start or stop a medication (I know I'm simplifying here) and on calls you would just try and keep them alive til the morning, as you're covering 8-9 wards on your own, then get shouted at by someone for not doing a discharge letter etc. I suppose when I was in GP, that's when I felt I helped the most people (but a lot of it through listening to them carefully). As for the re-assurance, I never let my doubts transfer over to the patient, try to appear confident, and obviously if I am in self doubt, call for senior help (maybe I do that too much as well !)
