Sadi's right. Just laugh at it and forget it! You obviously want this... and God willing you work hard enough you'll get it. TNA was joking but imagen when you are in Med school and you have a really grumpy consultant who looks at you like your hopeless, and says "You're a few currents short of a fruitcake, you'll never be a doctor"... it demoralising stuff. You have to prove everyone wrong. Dont forget your sense of humour, it'll keep you sane. Chin up.
