Anxiety over daycare

So it's 2:30 am and I am having serious anxiety over the thought of even possibly having to put my baby girl in day care!! She is a little over 5 months old and I'm going back to school to build on my nursing degree. The thought of being away from her for an entire day at school is just agonizing for me. I've been with her every day since she was born, and can't imagine it being any other way. I really am struggling with this ladies! Anyone else having trouble coping with child care?? Any advice/opinions welcomed! I don't know what I'm gonna do!!
