How would you feel about hearing that a GP had thought those sorts of things about someone else? If he'd told someone else they wouldn't hurt themselves because they have kids? I know how these things can shake you up. I really know that, but I don't think you should let someone, who is so unhelpful, steer you in the wrong direction. I bet your T thinks something quite different about what's possible for you and what will help you, in comparison to what this GP thought. I'm sure your T also knows you a lot better than this GP.
