Dont apologize. I feel your pain, stranger. My Mom is battling cancer right now as well and very recently her everyday communication has taken a sudden turn for the worse. My heart is heavy because all I do is constantly disappoint her. It's getting to a point where reality is finally setting in that she wont be around much longer.
I dont want to take away from your grieving process though, this isn't about me. I'm truly sorry that you had to go through this. I never even should have commented what I did.
This is a beautiful picture, and I'm sure your Mom is incredibly proud of you and what you did for her in her last days.
I'm so sorry OP.
