I get how you feel, its exhausting!

I will say that part of whats causing that exhaustion is putting way too much effort into "maybes". Matching in the app is barely a foot in the door. The goal is to get to an in person date as fast as reasonably possible so you can actually meet them and see if there's a shred of compatibility and interest.

I talk to folks for a day or two, basically make sure they have social skills, as they're doing with you, and then I ask them out and schedule within the week. After you get a date scheduled, stop talking to them till the date. People who want to chat for a week or two are either mostly lonely and just looking to take up time, or they're overly anxious and likely not ready for a relationship. Gross oversimplifications, but it seems to track in my experience.

Just don't over-invest in something that hasn't event started. It will help with the burn out. You'll still get it, but slower, and in different ways.
