HI A.,
It's the hardest thing going back to work or simply finding time to work...and not feel the guilt. However, it's time to realize that seperation is a healthy thing!
It's also a healthy response for her to cry when you're gone. You've been there every step of the way for her needs to playtime fun, and change is good.
I think we try so hard to feel guilty and let that consume us. If you're not ready to go back to work then try waiting to see if your mind will change any.
I wish you all the best in work, life, along with your daughter's transitioning. Hang in there-- it's hard but you are doing what is right, common, and best for your daughter.
Also, to take her away from family or people isn't realistic. She needs you up until that time you actually get in the car and drive to work. Instead look at it..have fun with your family make extra special moments leading until you head into work. That way she'll have positive memories of you. The week you start work--bring home something special to share with her to make it a happy move for the two of you.
I don't think she'll be crying for long. It'll be harder on you though so pack tissues and enjoy your time as an adult. Good Luck!
