That is a difficult stage to be at, I made a work around, following www.flylady.net on how to do amazing things like be organized, I have a list of the basic morning and evening routines in my bathroom.

Setting the alarm for what I think is a good time for me, 9:00 not thinking about getting up helps as the getting up becomes overwhelming.
I say to myself outloud "fly lady" and I do as much as possible on the list, and allow myself to go back to bed to 'reboot' on those especially difficult days.

My list starts with get out of bed, make bed, pray/meditate, go to bathroom, ....

According to a sleep study, setting your wake up time is the key to having a schedule. I started at 1 or 12 when most under the influence of depression and just started setting the alarm earlier by 15 minutes. After a few months I am now waking up at 730 on my own. (It is summer and that may change in winter) but my alarm is set for 9:00.

I am still sleeping 9-12 hours at night, I try to make 9:00 my bed time, and still have naps during the day, less now that I am really trying to pay attention to my anxiety level and not get past the point of no return.

A few minutes of focus breath work, making sure it is not past 3 hours without protein, is really helping to even out my day.

I have always been a morning person.

Hope there are a few ideas, that you can adapt for your needs.
all the best
