I'm so sorry for you. I know exactly how you feel, my dad passed away suddenly seven years ago at age 64, and my mom has had a very hard time adjusting. She was a stay at home mom and wife, and had virtually never been on her own. Things will be rough for a while, and your mom may be bitter and unlike herself for quite some time. Be there for her, and when you need some extra hugs and support we are all here for you. I'll keep you and your mom in my thoughts and prayers.
