I feel like I'm at my limit- I don't want to have to function anymore

I live alone, have multiple pets, and work full time. I often say I can be on time, well-rested, and fed in the mornings, but you can only pick two, and on a lot of days you can only pick one.

I tend to be a workaholic because it's stimulating, and also a regular routine allows me to structure my life around the hours that I know will be occupied. Even with medication though, it's hard. It's almost 2:00am and I need to be up by 8:30am to get my pets to the vet, go to a local hang out, get my nails done, and then get my car washed (after I clean it out) and then get the laundry that I've been putting off for a month done, picking up my pets, etc, etc, etc-!

I have no time to relax, and on the rare occasions I do, I feel like a failure for not being productive. I also like making art, but I've procrastinated on that too. I don't know how to make my life stable. I don't have a way to just relax because I'm always being depended on. I'm so tired. If I didn't have my pets, I'd run away and go live out of my car.

Yes, I'm in therapy. Idc. I still feel overwhelmed all the time, but I need money to survive.
