JM, so sorry for your loss...you'll be busy with the arrangements and all...when everything's quiet again, and your mom's passing really hits you, know that we'll be right here, with hugs and open arms...
Many of us have been through this. My mom passed away 33 years ago, and I still miss her terribly. So know that it's okay to feel sad...in time, you'll think of your mom and smile at a happy memory of her...
