One thing a day.
So at this stage in my life, in my 50's, having the longest and most intense relationship end suddenly with the death of my wife, being diagnosed autistic - life is down to one thing a day.
By one thing a day, I mean one major activity, be it work or play or anything in-between, there's enough resource / energy / life to do that one thing, and should for whatever reason I push through and do more than the one thing, then the 'tism-tax will be paid and I'll spend the next day pre-drained.
It's a new and harsh world, not having the energy I did previously... I honestly don't know if I'll ever be able to recover enough, if the 'tism will let me, or this is it.
So when working (yes, I have a job!), there's work which takes all the focus of the day, the bulk of my energy, processing, existence... and rightly so I supposed, as that's the contract which is work - work have a subscription to me which needs to be returned. For my daily cycle, work gets the best of me, before the point in the day where the processing costs cause the executive disfunction. Giving this portion of me to work for the work-days means everything is essentially on hold; other daily tasks, cooking, self-care mainly don't get done or are on a skeleton-crew basis.
Don't even go there with having a social life, there's no out-after-work, it's scurry home, sometimes 'tism-rage, and honestly sometimes what feels like stasis.
As I work early hours and finish by 15:00 most days, sometimes I can get in enough recovery on the work days to do another thing, properly hoovering or cooking, helping out a friend, working on a personal project - you get the picture. So yeah, one thing a day. From reading and conversations, I'm not alone in this 'tism world. Some people have less resource and are higher-support requirements, some more resource and have lower needs - if you've met one Ausistic person, you've met one - don't assume.
Days off are, for me, a race to get something done before the energy pool is empty... Being stuck in "Lark Mode" isn't fun; when I'm awake the world is just about blinking, and it'll be another 4 or 5 hours before I can engage, which is the middle of my period of usefulness! So It's a battle to do stuff quietly and early, saving the noise for later. One thing a day, two if I'm very very lucky, more than two = days of depleted resource and recovery.
