EDIT: please, if you don’t agree with the arguments in the video, come in and discuss, don’t just downvote the thread.
I found this video with many arguments supporting self-diagnosis validity and wanted to share.
Main point may be that there is no valid reason to look for a self-diangosis than the fact of being autistic, and needing support for that. At least until there will be equitable access to medical care, self-diagnosis is the only way for people to understand themself and understand the support they may need in their life.
But, there is much more in the video, take a look at it by yourself!
I mentioned on my first comment of this discussion that self-diagnosis is good for a person to get interested in the subject and learn more about which could eventually lead to an official diagnosis.
And part of my comment explained why this is not always an option.
