hey, I honestly get this. there were points when my guy was a pup and pushing the boundaries it was miserable. they are hours and hours a day of work and they can be kind of jerks, esp when they're young. he's settled down so much and I'm proud of him, it was worth all the work. don't be down on yourself for feeling the burn out though. I started paying a dog walker to take him out for the day once a week and it helped even having one extra day where I didn't have to worry so much.
edit: also when I got covid he went a week without a walk and didn't even complain. they can go a day if you're burnt out. it might be nice to watch a movie with her, just play with a ball inside or something.
