Aw Marti..., I am so sorry for your loss...! I lost my own mom 2 months ago, so I understand what you're going through! Nothing harder than losing your own mom... .
This is what I did to cope with that loss:
I put pics of her everywhere in the house, and I talked to her all the time. I talked about all the good things we had, about great memories. This worked for me! I've also accepted now that mom is in a good place now, reunited with all her loved once who died before her. She is painfree now, and is also able to walk again (she had MS).
My mom was 85; how old was your mom?

I am sending you feel-better-vibes and many big hugs ! Take care, okey!

Your mom was such a beautiful friendly lady!! What a sweet picture of her!!
