Self-diagnosed or professionally diagnosed, you are among friends here and people who are supportive and empathetic in your life struggles.
It has been repeated many times and I agree, that it's important if at all possible to obtain an assessment from a therapist who is experienced with adult autism and adult autism assessments. A dermatologist can't effectively diagnose kidney disease but is still a physician. I would argue that a therapist who works with autistic children as a focus isn't an ideal assessor for an adult. Many people have posted on autism forums that they have broached the subject of autism with their non-autism therapist, psychiatrist or physician and have been dismissed. "You don't have autism because you can make eye contact.", etc.
If you're in the U.S., every state that I'm aware of has an autism society. The autism society in my state is over 150 miles from my home. I chose to seek an assessment there rather than locally because of the experience the PhD therapists and PhD assessors have in working with adults (they have PhD level professionals that work exclusively with clients who are 16 years old and older and do not work with children. I felt the same way you do and as such, I wanted to go to the experts.
Keep in mind that a key diagnostic criteria for autism even for an adult is the person's behavior they exhibited as a child and that data is generally required to be supplied by someone else rather than the adult's own recollection (e.g. data supplied by a parent of the adult seeking an assessment).
For example, this is an unlikely scenario, but a person could believe to their core that they're autistic, but when the person's parents recount specific details about the person's childhood behavior and there were no autistic childhood characteristics it's possible that the adult would not receive an autism diagnosis.
I was raised largely by my mother who passed away prior to my assessment. Fortunately for me, she'd written a detailed baby journal chronicling my behaviors and I was able to supply those writings along with my other assessment documents. My assessor said my mother's handwritten notes about me from the age of less than one year to three years or so was very helpful and valuable in conjunction with the overall diagnostic criteria.
It's important therefore, in my opinion, for anyone who is on the journey of self-diagnosis to go all the way back rather than focus on who you are now. To anyone who still have parents that are living, I would recommend having them recount how you were as a child and to write it down.
First, thank you so much for the welcome. It's so ...I am used to feeling out-of-place.
This is all good advice. Coincidentally, I just got off the phone with my oldest brother who does have some memories, saying that I was unusual and just never managed to fit in or conform to what people expected me to do. He also told me that our mother took him to be evaluated for autism in the 80s and he was found to be "gifted." He was later diagnosed with schizoaffective disorder and is on SSDI. While I was talking to him, I remembered that I have a baby book that my mother filled out for the first few years.
I'll have to do some research on the following:
Ages 1-4:
Would seldom cry
Full 4-word sentences at age 2, reading independently at age 4
Sanguine affect (peaceful, contemplative) quietly looking around, but also affectionate
Serious and purposeful, problem-solving on my own
Obedient but quiet; my mom writes that she doesn't really
know me, she only knows
about me.
When there
was a tantrum, it was epic
Serious sucrose intolerance and malabsorption issues
Frequently wandered off without telling anyone where I was going
Age 5:
Extremely independent, difficulty "following directions", quietly does it my own way
Kindergarten teacher warns of too much daydreaming and no socializing or speaking in class
Writes that now I am extremely decisive in my preferences and actions
Hates dolls, prefers books
Doesn't tell pretend stories, prefers to tell real stories
Easily bored at school, testing above average academically
Some things are left out, such as my stimming behaviors, and it's tough to guess what she'd find worth noting, given that at least my father is neurodiverse. My mother prefers leaving out unpleasant or concerning things in any personal story, but this account is at least something.
I remember a quiet childhood, content to be on my own, often exploring an empty field or river bed. I did sometimes play with a friend, but definitely attached to an older brother when I was old enough. I'd follow him everywhere, it drove him nuts. And my favorite daydream was being a hermit.
My inner world was so vast as a child. It is still, but you know...I don't visit as freely as I did back then.
As for finding a doctor who has experience with adult autism, I will be pursuing that for sure. But now I've got to give it a rest for a moment, stop perseverating over my early years, and just remember to trust myself. This is tough.
Thank you again for the warm welcome and sound advice. And for reading to the end.
