Day care question Helpp

So my daughter (9 months) will be going for the first time to a day care. My sister is been taking care of my daughter since she was born and I got back to work but she is leaving to another state. Therefore, im been force pretty much to enter my baby in a day care. I’m a little scare and stress about is. I cant sleep. We found and “ok” day care around where we live. Pretty much 5 mins away and is on our way to work but i cant stop thinking abt it over and over I feel like im over thinking this too much. Plus she is now starting to have separation anxiety idk what to do. Any advice please
