That's really too bad he didn't take enough time for you to get what you felt you needed to get said/done done. I'd see what you can get done with e-mail and then make another appointment when you think you are feeling better to go there in person where you can be a little more assertive about how much time he gives you. Have you ever told him specifically, "I need 30 minutes/45 minutes of your undivided time" and gotten an appointment that way? I think a 30 minute advising phone call would be hard to do, pretty long; too bad you all don't have some sort of computer software so you could work back and forth using the computer instead of in-person or phone.
