Notice how this verse says "love your neighbor as yourself," not "before yourself" or "instead of yourself." Why is this important? Well, it means that in order to love anyone else, you must first love yourself and then use that love as a standard of how to love others. As I have noticed in my own life and in the life of other mothers (and women in general), we have a tendency to put the needs of others in front of our own. While being a helper and servant and caregiver are wonderful gifts that G-d has bestowed upon us, we can easily exhaust ourselves in the process of using these gifts. An exhausted woman has less to offer than a rested one. Believe me, as a new mother, I know what exhaustion is and I know how it affects my relationships with others. When we fail to love ourselves, it becomes very difficult to love others.
I would never suggest that you should stop caring for your children because your needs are not being met. I'm simply saying that you shouldn't feel guilty if you need a little "me" time every once in a while. That "me" time will mean something different to every woman. I'm not the type to go get a manicure or pedicure or my hair done, but sometimes I enjoy just doing laundry or a little shopping in peace and quiet... and alone. I am one of the reasons that laundry and dish detergents have so many fragrances to choose from. It's like aromatherapy for busy moms. I find that once I have enjoyed some time away from my baby girl or my husband, it makes me so much more happy to see them when I return to their presence. In some cases, the saying "absence makes the heart grow fonder" is true. It makes me appreciate my family even more.
So the next time you feel burnt out and exhausted, instead of feeling guilty, just remember that even the world's most powerful machines need to be refueled and maintained sometimes.
