The problem with online programs is that (from what I understand) they're not the same quality as "in person" programs and aren't taken seriously in academia. For example, the exams aren't procotored, and you can't defend a thesis in front of a committee online etc. Not to mention that a lot of these programs aren't accredited. They seem more designed for someone who wants to "check a box" for a job rather than someone pursuing academia.

Having disability accommodations from an in person school can eliminate some of these obstacles, however. For example, the exams can be protocored through Zoom either by the DRC or the professor themselves, and you can meet with you advisor/committee online and even travel once in a while in person to department events etc. (I have a lot of anxiety about traveling too, but if it was only once in a while, I could probably manage.)
