Thinking about quitting my job

I am a daycare teacher and work with 2 infants and 2 toddlers and I have my own child who is almost 2 years old.

I’ve been trying to hang in there and stay but I’ve been so Mentally and emotionally drained lately. We have a lot bit of savings and I think I want to take a break. Give my 2 weeks notice and just stay in with my baby.

My in laws got COVID and my child was exposed and I didn’t know and I feel so bad for exposing the other children at work ( me and my child go to same daycare).

I also feel bad for leaving my director without a teacher but I think I need to think about me and my family

What would you do?
