Emkana, I think PPH has a point (several points, actually). I think doctors can be uncomfortable when put in a position where they don't have the answers. Good doctors will deal with this by trying to allay your fears while explaining very clearly why they can't be certain. Less good doctors will deal with this by being defensive and displacing the discomfort onto the patient (or the patient's parent).
I think there probably is also a cultural issue as PPH suggests -- as you've found in the past Gm medics are more likely to have very definite opinions (whether or not those opinions are justified), perhaps because that's what the culture expects. Whereas Brits are more likely to 'fess up (at best) or dither (or worse) when they don't feel certain, and may react badly when put under pressure (as you've found out, to your cost).
And lastly, medics do judge, of course they do. Their perspective is different from yours. FWIW I was sent to see a psychiatrist at 20 because after 4 years of intensive treatment (including several major bouts of surgery, weeks in intensive care, months in hospital, a complicated and side-effect ridden drug regime and a delightful system of treatment throughout my university years involving spending one week in six in hospital attached to a plasma-exchange machine) I confessed to the consultant that I sometimes had trouble sleeping and felt that I sometimes felt slightly detached from normal life (no shit, sherlock).
Instead of having sitting me down for a friendly chat, pointing out that I had every reason to feel exhausted/anxious/freaked out, I had two psychiatrists put me through a full, unsmiling psychiatric evaluation ("do you feel other people are controlling your thoughts? Are you considering suicide? Do you ever hear voices calling your name?" blah blah). Having expected a friendly psychotherapy-lite chat, I was so completely unnerved by this that I said virtually nothing, all the while thinking, "Fuckin' norah, they really think I'm crazy, how can I get out of here?"
A letter was subsequently sent to my GP; she was less than entirely enthusisastic about letting me see it, but did agree. It said, in summary, "patient is pathologically secretive, difficulty forming relationships, hostile, blah blah, we would recommend further treatment". In the end I laughed what else could I do? at which GP was visibly relieved, and did say to me, "You're not planning to go back, are you?" A few years later, while weeding my brick-thick file of notes (paper in them days) she demonstratively put this letter in the shredder pile, saying, 'I don't think we'll be needing this again, will we?'
Moral (I know I've said it before): you need a decent GP who can understand your (perfectly reasonable) anxiety and help you negotiate the medical maze.
