I don’t recommend anyone leaves their job until they find another one. Even if you can afford quitting, unexplainable gaps in employment don’t look good on job interviews. If you want to leave, I recommend you start looking for a job in a public schools and you will likely find it at the latest by the new school year but possibly even now. There’s a huge shortage now.

I’d not say anything to administration though as you aren’t sure.

On the other hand if the pay is good and you don’t need to make more and you like the job, why not stay? I don’t believe it’s up to your mom or sister what jobs you work. So if no one taught at low income schools, how would the kids get education in those areas? It’s ridiculous they say that. I’d not based my decision on what they think.
