ok, so, let me just start out with this: i don't have a professional diagnosis (as of yet).
however, i have had multiple people agree that i have it including my therapist and mother.
i'm going to include a passage about why i'm confused and i'll try to space it if it gets too long (reading huge blocks of text isn't easy)
anyways, from the time i was little, my mom (who was in medical school at the time and worked at a hospital later), suspected that i had autism. i mean, i showed a lot of symptoms and traits of it, so it didn't just come from nowhere. she didn't want to get a professional diagnosis for me though (i think she felt confident enough that i had it to not pursue one; she did the same thing with my brother's add/adhd). she enrolled me in physical therapy for toe walking and motor skills, occupational therapy, and small groups to help me socialize
she didn't tell me until a short bit ago, though. i was always really confused why everyone always commented on me being "weird" or "quirky" or "different" and the like. around 2012, after someone told me that they "thought i was autistic" so i looked it up, and everything fit me and explained so much! i began to compile info on it and build a file.
this year (within the past month actually), i went to my therapist and asked her if it was a possibility. she told me she had definitely considered it before but we ran out of time and couldn't discuss it further. the next appointment i brought my folder in and gave it to her and after reading through it she told me she would discuss it with my mom.
she did, and the outcome was that they both agreed i have it, but they didn't think that me getting a professional diagnosis would be necessary, but that i pursue one in the future if i needed it.
so, would i call myself self-diagnosed, professionally-diagnosed, or is there some grey-area in between that i would fall into?
