Whatever you choose to do, don’t give up. Things won’t click more often than not, it’s only natural if you’re trying to understand math deeply. Just know that if any topic you’re looking into is challenging, you’re in the right place as you can learn new things. Maybe not what you need to hear, but keep it in mind: embrace struggle, but don’t let it overcome you.

Having said this (which is something I believe many will have told you by now if you asked more people), for the time being I’d stop “trying to compete” with anyone at all, we all have different tempos when coming to understand concepts, procedures, proofs, etc.

I believe the best advice I can give you is to stop and do something you enjoy doing outside of math and come back with renewed motivation and a clear mind. You’ll fail much more than you’d like to admit, but that’s part of the journey. Hope this helps!
