Having seen all those shiny, confident young people I'm also realising the absolute impossibility of ds2 (ASD) ever doing the same thing
Noits - don't say that! If you'd seen my ds2 yesterday afternoon you'd have seen a shiny, confident young person. I knew he was absolutely bricking it. His shiny, confident next door neighbour who was straight in when we arrived, talking non-stop completely overwhelmed us until I realised that his over-friendly, over-talkative demeanour came from extreme nervousness and he was probably also bricking it. The only other person who had arrived in their flat yesterday was a girl who apparently was too shy to come out of her room ....
When I went to uni many decades ago I made lots of really good friends and went out every night from the word go. Didn't stop me finding time every day for 2 weeks to ring my mum up and sob down the phone that I was homesick, didn't fit in, wasn't clever enough etc etc
Your ds2 may surprise you yet and, if he doesn't, uni isn't for everyone (my ds1 didn't go and would never have fitted in).
