Dawn, I am so sorry. I know there is nothing as great as a Mom.
Advice. I wish I had some. I am in week 5 of this myself. I think it just hurts. Don't grow impatient with yourself for not "being strong" or not "getting better".
Don't be surprised if you feel numb at some point.
Don't be surprised when one minute you are OK, and the next you aren't.
Grieving, so I am discovering, is a rollercoaster, and I am not rushing it. Take your time and know we are here.
Again, I am truly deeply sorry.
