But it doesn't mean you AREN'T a good player

^ what Nicki said. Your frame of reference has changed, that's all. You are a good deal closer to the standard of your heroes than you were - you just have a far better understanding of the distance still to travel!
Let's face it, most kids think they're awesome if they can play Twinkle Twinkle reasonably in tune. When you get to grade 5, you think you're OK, really, and that grade 8 will mean you're actually pretty good and well on the way to being ace. When you're at grade 8 you think you're not that bad but you know how great you're not, but you think that if you get to diploma level then you'll be a reasonably good player... having got your dip (with distinction, no less, so let's face it, two independent and unbiased examiners thought your playing was worthy of a professional qualification...) you're just so aware of the gulf that still exists between you and the greats.
BUT STILL. You can see with clarity that you're a heck of a lot better than you were even at grade 8, let alone when you learned Twinkle Twinkle! You got a distinction in your dip, so no matter how much you see the bad stuff in your playing, logic says there must be a lot of good stuff too.
I'm not trying to puff your head up to huge proportions, and to be honest I think it's really refreshing for someone who clearly IS talented to be so honestly modest and aware of their shortcomings too. BUT... evidence suggests you're still a lot better than a LOT of student cellists out there

Awww, cheers, guys! You've put a smile on my face now. Of course, my problem might be exactly that - I could be better than some student cellists out there, or cellists my age, or whatever, but I want it all!

When you get past a certain point, people shouldn't care what age you are, or how long you've been learning or whatever (though they often do) - I think that any players dip upwards should be judged on pure sound, and not the fact that they're 6 years old and have been playing for two and a half weeks (okay, maybe slightly exaggerated...!)
That's my problem with all these youtube posts saying "OMG I may as well just give up" - watch the video and okay, you've got a bucket-sized tot playing Rach 2 on the piano, but just listen, and you'd never listen to that kind of thing if it didn't have the label of child prodigy on it. Fine, it's all very impressive that they can get their hands round the notes, but once past a certain stage, people need to realise that they need to compare themselves with people NOT in their age-group. All only in my humble opinion, of course....
But anyway, this is why I'll never accept myself as a good cellist - or at least, not until I get to the stage where I could give a pleasurable and close-to-flawless recital where people would come and listen. Then, if I ever get there......actually, no. If I ever get there, I'll be wanting to play like Feuermann! But I'll be closer....
The reason I'm doing YMOTY is just for the very, very remote possibility of that concerto with a fabulous orchestra (maybe I should buy a lottery ticket for similar odds...!). Also, it should be good to get a programme together and as good as I can get. But I'm under no illusions!
