Dear Mom: Today was probably brutal, and you felt like you were failing as a parent. I feel you! Such days can be incredibly heartbreaking! You see, being a mom can be isolating at times. It expects more from us when we feel we have nothing more to give. It is exhausting and frequently undervalued. And despite being one of the most exciting and fulfilling jobs we will ever have, motherhood can still put our sanity to the test. On days like this, we just snap! We yell, get frustrated, or let off steam at full throttle.
