After a melt-down I have to spend a day in bed, with my phone off.
I do that as it enables me to return to a normal level the following day.
It works because there is no external input.
Yes, when I'm in bed for those 24 hours my brain is active, and I think about things such as "How do clouds stay up in the sky?", "How does the Earths spin effect gravity?", "I wonder how recycling is sorted", and lots more.
The KEY though is that durin that time there is no EXTERNAL input.
My brain is able to go through on probably a subconscious level what caused the meltdown, whilst my brain keeps my conscious mind busy with thinking about the sorts of stuff above.
Thankfully I don't have a meltdown that often as I avoid situations that could cause it.
However, to lead a life of integrating with NT society I do make sacrifices. In other words I do sometimes place myself in situations that NT's do in the hope that my ASD mind may learn how to cope with them.

We, the people on the Autistic Spectrum have a choice.
We can either try to "fit in" with the rest of society, or we can be so egocentric that we can't be bothered.
I choose the actor. I observe NT's. I listen to their socializing. I practice it, so in social situations I can just emulate/mimic what is expected.
It isn't natural for me, but it enables me to "fit in".
It is VERY tiring and draining, but at least we can appear like them even though it is an act. Like being on the stage.
They can't see it is emulation, and so we are accepted.
