Yeah, I guess we are. I can look back to a lot of stuff and hate myself for it but most anyone does that. I'm happy that you're doing well and coping with issues thrown at you, and I'm glad that you're working on being more confident. That is something that has been troubling me for years as well, you were correct to guess that, but I'm also looking to do more also, there's a lot I stopped myself from doing in the past due to being shy and uncomfortable, as well as other personal issues, and those things I stopped myself from doing can seem pretty silly things to say 'I shouldn't do that' to when you'd otherwise want to.
My twin's also doing computer science stuff at uni and he's enjoying it and doing well. I won't be seeing him until December and he's been gone since late September so I miss him. Was the first year easy to get into? (And that sucks about you having to spend an extra two years during A-levels, was a lot going on at that time?)
I may try to talk to some of your friends but I won't guarantee anything. Maybe if I start posting more and seeing them about, I'll consider it.
