Apologies if this veered too much off topic. I've been kicking this around for a week or two, and felt the need to add recent events and post.
It's 5am, I haven't eaten in 12 hours, had anything substantial to drink in about 8, have been sitting on the toilet for over an hour, and instead of doing something about any of those things I'm editing a comment to fix a typo.
Getting a dog has helped me in ways I never expected. I just figured "cute, cuddle, good for brain chemicals". But they HAVE to be walked at a certain time. They HAVE to be fed at a certain time. Regardless of any of your internal issues, you love them and you have to provide for their needs.
So when you are in the kitchen filling their bowl, you make yourself some toast or grab a banana. When you are taking them for a walk, maybe you go a little farther because they like it and it's good for you. If you struggle to get up in the morning, they look to you pleading to be taken out to pee and you get yourself up and dressed. They need training and that requires being consistent, so you do it for them. It's so much easier to do it for them than for yourself.
To add: they're extremely good at noticing when you're feeling down and will try to help.
This worked for me, still dealing with a lot of issues but there is atleast a hint of schedule. And one of of my two dogs is extremely finicky about time. She has to be out the door even if there no poop to be shat.
