I wonder if AS that is undiagnosed early can lead to other problems developing.
The pressure to conform, to go to university, get a good job, work your way up a career path, get married, have children. These are potentially difficult because they involve lots of social interaction, and can be high stress. I had anxiety from early childhood, which I tried to surpress, and fulfill the targets I was supposed to be aiming for as a middleish class woman. But it was always a struggle, and I had frequent periods off sick from work, relationships fell apart, I ate too much to try to comfort my feelings of failure. I had a huge breakdown a few years ago, from pushing myself too hard, and staying in a job that was killing me.
Now I am a total recluse, the opposite of what I should be, according to the norms of the world. I have a diagnosis of BPD, GAD, and others. Yes, I think if I had been diagnosed with AS when I was younger, then maybe I would have been kinder to myself, realised that I am different, and that it is fine to be different. Just find the place in the world where I feel most comfortable, instead of striving to be like everyone else.
