It might help if you put your mind to the subject of specific problems you have encountered or can foresee, and using that to draw up a list of 'ideals' to take into discussion with her. These can then be discussed and the 'possibles' kept in mind. Then it would help if she actually pro-actively did something about them! -- what are you mean to do, administer your own education?
For perspective, I have had similar problems with my university's disability department, and found that drawing up a list stimulated them no end. Having a written 'proposal' means it goes on file and is a registered set of needs from the student.
If you have a personal AS advocate or similar, it might be helpful to take them along to the meeting.
