Another argument is that you are denying yourself of the experience of being human. These feelings exist for a reason, just as physical pain exists for a reason. You wouldn't hurt yourself on purpose (or maybe you do c;), but physical pain helps you stay safe. I feel this is the same purpose of negative feelings.
Finally, I have found out that suppressing these feelings does not allow you to fully process and heal from the events that trigger them.
In the context of "denying it exists", yes, it's clear to see that it's not possible to process the negative feelings if not explored.
But the positive interpretation would be to not spin on these thoughts endlessly. It's a trap for all of us and obsessing over hurts doesn't serve us well either.
I have a theory I call "the emotional digestive system": we take in these hurts, taste them, chew on them. Then they digest. If the process is working well, we shit them out.
The way out is agency over how you deal with reality, not better blindfolds in the short term.
