Ds has done well in his A levels after ballsing up his AS's last year and has got in to his first choice uni on the course he always said he wanted to do. Hooray. 
Except now he's panicking and doesn't want to go to uni at all and is sat researching his imaginary travels in South America. 
His reasons are: 1. He's had enough stress for a year or two and doesn't want more stress of doing a uni level academic subject. (fair enough?) 2. He's worried the other students will all be more advanced than him (totally unfounded anxiety).
Anyone words of wisdom? Anyone else got a panicking dc?
Feels like I'm re-living the stress of results day
