Anyone else struggle with routine when on their own (ASD)

[Bridgertonned]

Just curious if anyone else experiences similar. Off work today, DH is away, and as usual when I'm on my own (no kids) my routine disappears. Wake up far too early, look at my phone (so can't get back to sleep). Get out of bed 4 hours later than usual. Snack on junk instead of meals. Nap at 5pm and now wide awake when I would normally be going to sleep.
Haven't managed a proper meal or any household tasks. It's not that I don't allow myself a lazy day, more that this isn't an intentional/indulgent day, feels more like procrastination/passing the time.
On a typical day with people around I eat well, sleep well etc.

I have noticed this in the past (pre ASD diagnosis) and thought it was related to my upbringing (without going into details was neglectful, so perhaps not good at prioritising my own needs) But I'm curious as to whether this is something experienced by other people with ASD. It almost feels like I need other humans around me to remind me what to do and when!

I get this with ADHD - and in reverse too e.g. if I have managed to get a little routine going, then as soon as someone else is present it all goes to pot and nothing happens as I had intended.

It could be when people are around they are sort of "body doubling" for you?

Or I think for me when it happens both ways, it's mostly about a sort of disruption to the expected routine that kind of "resets" the situation for me and I don't know what I'm supposed to do and my default is to do all that nothingy/procrastination stuff.

Thanks for the response @BertieBotts I think the procrastination is definitely part of it, and the routine change - almost like there's too many options and the easiest is to look at my phone. And 'body doubling' makes sense! I usually think I have quite a fixed routine so I find it strange how quickly it disappears if left on my own. Feel a bit like a child!

I’m the same. I force myself to do things that I find difficult because my family needs me to. I cook for them and I eat some - but I wouldn’t cook just for myself. They prompt me when it’s time to eat - left to my own devices I would forget. Without their intervention I would get absorbed in something and sit there working for 20 hours without eating or getting washed or sleeping. This type of obsession is both a blessing and a curse.
