I'm not sure if this is technically "advice", but-
When I was starting to make the decision to return to college as a full-time graduate student, I was discussing the idea with friends in my narcolepsy support group. I explained that my undergrad was a trainwreck (prior to my diagnosis and graduated without my intended degree because I was not in a healthy place), and although my dream to become a music professor meant lots more school, I wasn't sure if I could do it.
Long story short, I was being very hard on myself and beating myself up about how I didn't believe I deserved accommodations. Finally one of my friends said "Gabrielle, you have a disability. People with disabilities get accommodations because they don't function the same way people without disabilities do."
It honestly hit me like a train. I was like "woah... I DO have a disability. And as a teacher, I would never look at my student any differently if they asked for accommodations due to a disability. So why am I expecting myself to do so much without any help?"
Ever since then, I have learned to give myself grace and (try) not to be so hard on myself when I know I need help. My professors have also been extremely supportive of me and understanding my diagnosis.
