Work, Work, Work

For anyone that knows me, they know that I love my job. I absolutely love taking care of my patients and love making a difference. Lately, I have been working so much. I have been going in for meetings, classes, training, and working when they have been short. It has worked out great because my sister and brother have been coming over to babysit her. I am only part time but have pretty much been working 50 hours a week. The paychecks have been more than great and I am beyond thankful that I have the opportunity to make this money in such a rough economy. The only problem is that when I work so much I feel like Jamie and I disconnect and I get heartbroke and sick missing Grace. This week I scheduled myself for my two part time shifts and nothing more and it was BEYOND great to be home all week. Jamie and I did something fun and relaxing each day and it was just so nice to be home. The problem is that my work called me all the time this week (both places, St. Mary's and Shriner's) to see if I could come in, and it takes all that I have to tell them no. It is so hard for me to disconnect the loyalty I have for my job and my job as mother and wife. How did everyone do it all these years. My mom always worked full time as I was growing up and I never felt neglected--it was they way it was. Why do I feel so bad about it???? Anyone have any advice??
