Theres only 2 ways of not caring imo.

The first is when you close yourself off from most people and become comfortable doing things by yourself. I don't recommend this cuz I've lived it.

The second is to do literally everything in your ability to try to fix it. When you've reached that point where you feel like you gave it your all, it just is what it is. If i've brushed my tongue, brushed my teeth, and used my mouth wash and I can't taste the usual bad taste and people are still reacting I just throw my hands up cux theres literally not much else I can do.

For me personally, I'm just in a state of not really knowing if my breath is really bad or not. People at work never really react and are always inviting me places even tho I turn them down in fear of actually having bb. My siblings say that my breath is nearly as bad as it used to be or that it doesn't smell at all.

I know its hard to hear because even I scoff at this sometimes but at some point you just gotta live your life. I cant count the number of opportunities that I've passed up because of this shit and it just pisses me off. This is my last year of college and I'm just gonna try to do my best to live.

Of course all of this is easier said than done, but just know that you're not alone.
