Disagree with the premise here.
There are people I would phone at anti-social hours for them, in circumstances where there was a good reason for doing so [say, to pass on information that couldn't wait till a more awake hour of the day].
If I want support for me, I much prefer getting this in text based format online, from people who happen to be awake and with it at any given time of day.
If I want telephone based support for me, I'd much prefer pre-arranging that with the specific person I want support from at a time when we're both awake. Waking up sleeping people for my own benefit isn't OK and is detrimental anyway - I'd rather have a conversation with/support from someone well rested, than wake someone.
My other technique is to sit and write, often by hand, to order my thinking.
I don't ever 'need' to talk to someone by phone at anti-social hours for my own reasons, because there are other ways for me to find support for me that suits me better.
