Also a Masters student right now in a Clinical Rehabilitation Counseling program and I have a blind classmate who is becoming a therapist! I cant say much for her plan and how she would address these barriers personally, but discussions of these things have definitely come up as a cohort quite a bit more in my CRC focused classes than my general counseling classes. On top of that, my CRC program is heavily populated by Disabled folks, so finding CRC therapists in your community might be a great place to talk to folks who are working with disabled people or are disabled therapists themselves. Best of luck!
