Need advice😢 and support

I gave birth 11 weeks ago to a beautiful baby girl. Weve spent every day together bonding and loving eachother. Shes a total mamas girl. I have to go back to work tomorrow and im so anxious about leaving her. I have a great day care lady set up but im so nervous my babys gonna have a hard time.

Any of you ladies gone through this? How did baby react? Is she gonna think i abandoned her?
