Thanks, everyone. It's a relief to know that others have the same issue due to a fear of manic spending. I think I'm going to earmark a small portion of my budget for spending on myself. Maybe that will help me get over the anxiety.

I've decided to use the money on something mom and I will both enjoy. I don't know what yet, but I think it will keep me from feeling the guilt that comes with spending the money on nobody but myself.
