I have heard from a few different sources about the first 6 months after an autism diagnosis being the toughest. Adjusting to this new perspective and even giving myself permission to be who I am is sometimes disorienting.
I spent my entire life hiding who I am and how I see the world because it didn't conform to the rest of society. I know I am a bit of a "lefthanded monkeywrench" but I suppressed the comments and observations to fit in and not alienate others. I also hid my love of certain subjects from everyone but family and very close friends.
I felt people wouldn't understand or worse, openly ridicule. My fears also kept me from pursuing a route that would help me find a measure of peace. I can remember at least 3 to 4 major depressive episodes in my life all came about 5 to 7 years apart and one of the last ones was bad enough to have me seriously considering how to exit this life. Part of my belief system says that if you check out early, you have to eventually return to make up for what you did to harm others, and what you didn't accomplish. The idea of having to come back was more than enough reason to tough it out. But that didn't prevent me from having a exit plan.
When I finally accepted that autism might be the main reason for my depression, I didn't want to believe it. But when I confirmed it with the psychological tests everything changed.
Have you ever spent a long time in a noisy environment? Many people eventually learn how to tune it out but when the noise stops suddenly its absence is distracting. That's a little like what learning I am truly autistic is. The problems come after the realization.
I have spent half a century suppressing and observing. I believed that the mask I wore was what everybody experienced. I even marveled at people who seemed to respond without having to consult the inner filter. Then I learned that most people don't have on because they don't need it. They have an intuitive knowledge of the rules. The same ones I took decades to learn and craft into a convincing façade of the average person.
What bothers me now is the realization that I can't go back to that person I was. My existence has outgrown the restrictions and now I can't get back in the bottle. But along with that come a distression realization of limits I felt I could ignore. My skills seem to have regressed and I am not able to mask like I could.
