I'm sorry you're going through this.
Have you considered some sort of intensive outpatient program, or maybe a support group or 2? That might be a good small start, not as hard as work but something you'd "have" to do some days to help get you going.

Not sure if this would help, as personally it's not usually enough to get me going ha, but you could also look for a good alarm clock app. There are some that will let you print and stick a QR code somewhere, like for example in the bathroom, and then the alarm won't stop until you get up, go to the code, and scan it with your phone.
