Advice please

I’m returning back to work next week and I really don’t want to go and leave my baby she’s nine months old and she doesn’t sleep anywhere but her crib. My parents will be watching her which I’m very grateful for but at the same time they’re in their 70s and basically have used up all their babysitting time with my sisters kids and are basically burnt out. I just went there today just to go to the dentist dropped her off and she hated every minute of it was crying her eyes out. I have such anxiety I don’t know what to do - good thing is I’ll be teaching live from 9 to 1145AM which is not horrible but I know she’s not gonna nap and she’s just gonna be miserable can someone please offer some story of their own where their child was like this and then got better or just some tips
