I am so sorry about your pain, I know exactly how you feel. It just takes time and after that some more time. I promise you, that ache will go away and you will be left with cherished memories.
The heart truly can heal and then you are left with peace and a smile...That peace and smile will shed light onto Matty.
Give Lady a big hug as she needs you now....We are all thinking of you.
Schatzie sends her hugs.
