Cheesyt, I agree with Hawk. It's very possible your W didn't give the gift to your D. I would be hesitant to read into this that your D is against you now.
You say your D has a phone? Have you talked to her on text since you last saw her? You could always send her a text saying "hope you enjoyed the book I sent!" Just a thought. My D is about the same age and she loves it when I send her cute cat memes. Maybe even opening a dialogue with D by sending cute/funny pictures might help.
That's awesome news on the 1/2 marathon. I've thought about doing that but it kills my knees running on pavement. I tend to stick to trail running and the treadmill. We do need to get a tough mudder team together though!
Keep being strong cheesyt. You are doing right by yourself and you should be proud!
