Finally got a Job, but now im so Depressed

I've been a stay at home mommy for 6 months, frantically looking for employment nearly the entire time. I finally got a job! I thought I'd be so ecstatic.... But now the thought of leaving my baby girl during the day is breaking my heart. I'm getting anxiety, depressed, keep crying. I know there are so many working parents out there, and I always planned on being one too, but its a lot harder than I thought 😢😭
