Feel guilty taking me time???

Genny
It's 3:36am and I'm wide awake sitting in my beautiful 4 month old daughter's room listening to her sleep. I'm having anxiety and am beating myself up because my company had a golf outing today and I had a couple of cocktails with my coworkers. I wasn't hammered but I did catch a slight buzz and made the decision to stop drinking so I could get back to "normal" asap. Even though my daughter was being cared for during that time and was/is perfectly safe I'm really mad at myself. I feel like I lost control for a moment and if my daughter needed me I wouldn't have been able to truly be there for her. Also, full disclosure, we live .5 mile away from the golf course and I walked both ways so at no time today was I, my daughter or anyone else in harms way by my actions but I just feel so guilty! Any other moms struggling with finding a balance between "me" time and "mom on duty" time? Or feel guilty taking some time away from their lo every now and then? Now that I've vented maybe I can get some sleep...
