Hey G, you are an amazing woman. Dont ever forget that.
Now, decluttering sets my heart afire - LOL! So, if you need tips, just ask.
My mom is gone a long time too, my dad even longer. It is hard, isnt it? But I really feel my mother's presence often. When I am really stressed or unsure, that's when I feel it the most. She is there for you. Mom's always are.
G, try not to keep stuff you dont really need or want. Memories are in your head. Save the stuff that is really special, get rid of the rest. Whether you move or not, decluttering and letting go of stuff is a fresh start.
You are going to be feeling a lot of different emotions in the process. Move through them.
