I'm not personally familiar with student support, but for everything else, most people are fine with it. There'll be bumps along the road and periods of doubt in everything - I had a nasty case of this a few weeks in and wanted nothing more than to go home. But I stuck it out, made some kind of an effort and I've just finished year 2 so... It's just a hurdle to be used to it, then it should stabilise for most people.
Having said that, not everyone will have a good experience or will transfer somewhere else or decide that uni is not for them, and that is fine - it doesn't mean that there's something wrong with you. It's important to communicate these feelings with someone and be able to make the right decisions, rather than doing it on a whim.
