Just a bit of venting(idk I'm upset)

My grandfather is one of my favorite people. I'm closer to him than my own father. He has dementia and various other health issues. In December of 2018 they said it had 6 months to a year. I'm so grateful we got this extra time with him. We thought he would make it to the wedding. Besides his dementia he was overall well. He had a very sudden turn. Within less than a week he went from the hospital to hospice. I was with him all day and evening and I'm back at the hotel. (We don't live in the same city so we drove and got a hotel). My heart is broken over this. He was so excited to be there with me. He couldn't remember a lot, but remembered I was getting married. I'll do some sort of memorial at the wedding for him as well as my grandmother(his late wife).
Hug your loved ones. There is never enough time. I am so grateful I got to have these 28 years.
