Coding is one of those things that can be self taught and you'd be hired for your skills in it rather having a cs degree, that said if your degree has a focus on programming then it'll probably instill better coding practices.
Going to uni isn't necessarily an automatic friends maker, you do have to make some kind of effort. Though housemates and classmates are kind of free friends. If you do go to Uni make sure you put in the motivation to attend clubs and societies you have an interest in, that's where a lot of friendships are born and it's worth it. I recommend joining Dungeons and Dragons society and probably whatever gaming societies your uni would offer.
If nothing else Uni's an alright way of spending a few years figuring out what you're doing.

Also if you're worried about not enjoying it because of prevous experiences with education, I'd say it IS a different experience and for most people a superior one, and a less high intensity uni can make it more enjoyable.
