I had a similar situation; lived in halls, made no friends, got depressed, decided to stay at home. It actually made things worse because being at home made me feel more isolated and depressed so i went back to a different hall and did make a couple friends but by then i had spent so long being depressed that i flopped the course and had to drop out.
I say try a different hall and if that doesnt work then drop out. Sounds extreme but even my professor told us all on the first day that if we arent enjoying it we WILL flop and he was totally right in my case. Better to leave and start again when feeling better than stay and end up with a 3rd class degree because your mind wasnt focused.
Also forget about university counsellors i always got a strong paid to care vibe from them, their advice is also pretty basic and unhelpful: "just look on the bright side!"
Ill get a lot of hate but honestly dropping out is an option. Everyone will always say just stick it out because they arent in your shoes crying yourself to sleep and eating till you throw up. Ive never once regretted dropping out.
