I feel you! I am a founder, in my 30s currently; I started building at 24.. Sounds like you have users, are they paying for your product? Is there a way to get it to break even?

First, you haven't failed; based on what you shared, you've built something people use. Of course, that might be different from building a sustainable business, but it is not a failure. Most people in the world do not even try to build something, so if anything, you should be proud of yourself.

I've been in your shoes, I had a product people loved to use but were not willing to pay, it was costing me my mental health and my economic stability. I decided to wind it down, it should not cost your life, you are super young and have a lot of time to keep trying things, maybe in the future you can revisit this idea and perhaps it would be a better time for it.

Take care of yourself! Sending good vibes
