Get him to go to Tai-Da. You'll have to make an appointment for him because he won't be able to deal with it. He will just stop, once the meds kick in.
I'm sorry to say, this is just how unmedicated, severely depressed people behave. They're a horrible, idiotic pain in the arse. I know he's not really your problem, but if you could just help him get meds and then give him two months for them to work, I think you'll see your old friend back. These are symptoms and coping mechanisms. He is NOT going to 'snap out of it': he knows and feels horribly guilty for the effect he's having, he just can't help it.
Tell him he has to go to the hospital or you are leaving (I know it's not fair, but kicking him out is not really feasible) He may just really not care, if he's very far gone. Also, he knows what he's doing, and that will be feeding into his loop of bad behaviour, so try to just ignore the stuff he does, if you can.
And sell his laptop. You need rent money, he needs to not be distracted.
Xanax and Prozac are 'old' drugs. There are also much better things out there now. In terms or counselling, there are a couple of non-retarded counsellors at the community centre in Taipei. Once his meds have kicked in, you should get him to go there. He'll probably be resistant (it's tough being helped to tie your own metaphorical shoelaces by some touchyfeely ****) because he'll have had counselling before and it obviously hasn't helped, but explain that it might be different, this time.
Also, if he really has an IQ of 140, try and empathise and imagine how painfully difficult it can be to be like that, as someone in his early 20s. He is 40 points away from the average. If you see yourself as average, or even above average, imagine what it feels like to be surrounded by people with IQs of 60 or 70, all the time. Also, he is in his twenties and has just emerged from a childhood with absolutely no boundaries because he's been smarter than his parents and teachers, and has never had to try at anything because he got A's in school for everything on the back of a good memory and general knowledge. He's never learned to share, never heard the word 'no', never learned to try and never failed at anything. Most people figure this out as children.
