Daycare! Please help!

My daughter is almost four months old and I feel like now is the time to return to work. I don't have to but I have an amazing job and don't want to pass up the opportunity because I know eventually I will have to return plus for my sanity. I want to hear positive situations from mothers who use daycare and was as nervous as I am right now. We are shopping around at day cares and will chose the best one for us but I'm still scared to leave her. I'm not away from her much because we live away from family and it's only me and my husband. 
Thanks! :)
