I know when I go to the gym while my kids are in day care, I feel "selfish"....No matter how many times I tell myself that it is important that I am healthy and have a release for my stress (other than coffee or chocolate!), I still feel guilty. And I have tried to plan a trip for me, just me, but I always wind up thinking of where I could go with my kids...
It is hard to remember that taking care of yourself and finding fulfillment for yourself is not selfish. I am glad your counselors gave you 'permission' to take care of Maria for a change.
