My mate is going in September. He had anxiety and depression for years, I managed to convince him to see the counselor at college last year so now that it ended he decided he wanted to see the doctor before he goes to uni. Obviously it's not easy for him but he wants to go and he took some steps to make the process a bit easier. Like getting some pills to prevent his anxiety attacks that he didn't realise he had.
He'll be moving into halls into an ensuite room. And when we talked about it he's mostly fine. Worried about finding friends as he's not into drinking but it's pretty normal. A lot of his anxiety is from family so maybe the distance will help. But he's at the point where he's willing to ask for help if he needs it.
Since I'm not the one in this situation I can't really say much else.
