My dad passed away from glioblastoma 2 weeks ago. My mom and I spent every day with him before his passing which helped us not live with any regrets after. After he died, my mom and I would do things he loved to do. It was painful do those things knowing he wasn't physically there... but it was comforting to do them as a way feel his presence. My dad loved camping with his trailer (I know nothing about trailers). I spent a couple days going through all his tools, learning how to setup a trailer and properly hitch it, then going on a camping trip for a few days with my mom. I don't think we will ever get over his loss but its nice to do things that you think would make him proud.
