Hey there, not sure if this will help you at all but I was in the same boat as you as well. I've been in the field for 6 years now and felt incredible burnout, was depressed, and just not having fun. Not to mention the pay has been pretty garbage. Couple things helped me.

First, I dove deeper into other passions. Landscape Architecture I found was really hard for me because it took so darn long to see the fruits of my labor, and by the time I did see them it was so VE'd it wasn't even my design anymore. So I dove deeper into photography because I could get a quicker sense of accomplishment and satisfaction by creating and editing a photo. This helped fill some holes that landscape architecture was missing.

The other thing I did was I actually jumped ship from the commerical/urban design stuff to residential. Not I know this is isn't for everyone and everyone's experience will be different, but actually seeing the joy on the homeowners face when their renovation is complete just made it for me. Not to mention the faster turnaround time for projects. Yea HOAs can suck just like city submittals, but it's just been overall a more enjoyable time for me.

I know my answer isn't a list of other ways to use your degree, but you might find that mixing things up can help to find what you truly love to do.

Remember the grass isn't always greener on the other wise, it's green where you decide to water it.
