Glad you liked the comic strip Heartofstrings* It's a good one to share with children too, to help them understand that in a lot of ways they are just like their peers and in some other ways, they are different and that's absolutely fine.
Also, as much emphasis as you can, built up over time on why "different" does absolutely not mean "wrong" can help kids whenever they feel as though they are out of step with their peers.
Try and find a lot of examples of different things that can achieve the same results, e.g. electric cars and petrol cars can do the same thing, but they are powered completely differently. A Mac computer processes things completely differently to a Windows system, but they can achieve the same results.
I figured that because I have a job, friends, kids, the lot, it wouldnt be valid if I got a diagnosis. I dont experience the same level of challenges so it wouldn't be fair
This is meant in the nicest possible way, but you seem to have a very fixed idea of what autism is, alongside a misplaced sense of fairness in that you want to compare your challenges with what you perceive other peoples' challenges to be. Autism rarely presents on its own, so again you may be looking at other people who you believe to be autistic, yet you're actually seeing symptoms of their co-morbid conditions, not their autism.
No two autistic people have exactly the same challenges and strengths and their presentation of their autism can be completely different. I've seen posts on the SN boards from parents with 2 autistic children whose presentations are like chalk and cheese, but they are both diagnosed autistic.
What would be fair, is for you to have an assessment by medical professionals who can, via their different tests, determine whether you are autistic or not and (hopefully) provide you with a barrage of test results showing your individual pattern of strengths and challenges which will help you to appreciate why you react like you do in some situations.
Please understand that if you do not fulfil the criteria, you will not be given a diagnosis. You will only be given a diagnosis of autism IF your scores on their tests, personal observations and sometimes historic evidence provided by a family member are within the ranges for a diagnosis.
Just going for an assessment is no guarantee that you'll get a diagnosis. I'm stressing that point because so many people think that all you need to do is have an assessment and then you will automatically be diagnosed, especially if you've paid for the assessment, it really does not work that way.
