Here's what I did: I'm already on social security disability so before I could get financial assistance my pdoc had to write a note saying it would not be detrimental to my health. He scribbled 2 lines on a prescription pad and that was good enough.

I gave that to my Texas rehabilitation commission case worker who asked for more information...like what accommodations I might need. I had my T write a letter explaining a little about bipolar disorder and how I might have a panic attack during class or need an extension on a project if I was having some mood issues. So basically my T did all the explaining the pdoc just verified the diagnosis.

I then went to the student service center and filed the paperwork in accordance with the ADA. I had to go in each semester and get a piece of paper filled out with possible accommodations (just in case) for each teacher. The first day of class each semester I took the paperwork to each of my teachers and explained that these were just-in-case measures and I did not anticipate having to use them; I just wanted my professors to be aware.

None of my teachers really treated me differently except for one a@#hole who I had to turn my first paper into late. He then called me on my cellphone outside of class time to ask if my second paper was going to be on time. Just because he made me so mad I turned it in early. However, this was an isolated incident: that particular professor and I didn't get along. He told me I'd never graduate because I couldn't get along with people (group work problem). So I made it a point to find him at graduation to rub it in his face :-)

The point is that with the exception of that one professor I never had a problem with my teachers knowing. In fact, it was kinda a relief because I didn't have to worry about what-ifs I could just do my work. Try getting your pdoc to simply verify the diagnosis and your T to do the explaining. Worked for me. Feel free to PM me if you have any questions.
