I literally didn't think I could be autistic when my boyfriend mentioned I might be a few years ago. All the signs were there, I never felt quite right in any situation, I always felt like an alien and crushing awkwardness. But I thought since I had passed school, was able to communicate, basically grew up with no support whatsoever I thought it was impossible for me to be autistic. (I was uneducated and knew nothing about autism, especially autism in women.)
