Can't catch a break

We just have not been able to catch a break in my family 2 kids one almost 3 the other 8 months old we have been sick NON STOP since October. My 8 month old has had a cold , ear infection, Corona virus, stomach virus, and now the flu all since October. My 3 year old has had 3 stomach bugs, Corona virus, several Colds (waiting on him to get the flu now too) when will we get a break?! I pray and I ask others for prayer and I give thanks and here we are still getting sick. It's so exhausting mentally and physically there's nothing more I can do. I feel like i can't be a good mom bc I'm always sick and no sleep trying to care for others who are sick with no sleep it's just Neverending cycle. Me and my husband are constantly fighting about sleep bc he works and I stay home my sleep doesn't matter to him and there for I should just suffer and be okay with it.
