So long as you don't expect the NHS to fund another appointment for you
What a horrible thing to say. 
FFS, the OP had suicidal thoughts after feeling like she was being told very little is wrong with her!!!!

Can you see your GP to ask to see another specialist? My friend has a chronic illness and goes to a clinic every 6 months for assessment, and to monitor it, and last year, she saw a 'specialist' who didn't make eye contact, just ummed and ahhed, and said 'do you want a steroid injection then?' after she had said 45 seconds before that the last one made her ill and she doesn't want another one.
In addition, she told him her joints had been very stiff and she has been sufferering pain in her hips and hands. The write-up for the file and the GP, said 'Mrs Smith has not reported any issues.'
The twat had not listened to a WORD she said. She made it clear to the clinic that she was pissed off and angry (a few days later,) and she was never allocated that man again.
Maybe, if it's too late to do anything about it now, go see him again, and if it goes badly again, put in a complaint immediately and say you never want to see him again, as he is not doing his (very well paid for) job correctly.
Me and you, and many people on mumsnet are funding this fucking donkey! Don't put up with it!
