Yes, it happens to most of us at one time or another. I hope things get better for you. Is that a picture of your beautiful DD in your siggy? If so just thinking about how fortunate you are to have her might help a little. Sometimes it also helps to just feel sorry for yourself for a little bit. No matter how blessed you may appear in other peoples' eyes doesn't mean you don't have a right to feel badly about things every once in while. Take care of yourself.
