I grew up holding the burdens of functioning labels. I was considered moderate to low-functioning (really?!) when I was younger at the time of my diagnosis. It wasn't until roughly my early teen years that I began to reject functioning labels.
Anyway, like others here on WP, I see problems with the "levels" system listed by the DSM-V. How could just one support level possibly fit one autistic person all the time? I could be level 1 most of the time but level 2 when suffering from severe anxiety or depression like I did recently. The levels system also doesn't account for comorbid conditions possibly affecting a person and how that would change one's support level.
(Sorry about the tangent. I wanted to explain a bit of my backstory to make it easier for my words to be understood.)
