SOLVED. A book about a boy with cancer who has a list of things to do before he dies. [s]

I'm looking for a book that I read a long time when I was younger. As I have said in many book search requests before, it must have been published before 2010 for me to have read it.

It was about a young boy who either found out he has cancer, or he has had it and was getting weaker. All I know is that he had cancer and was getting weaker and weaker. He had to have been no older than a middle schooler. Anyways, spoilers for the rest of the book but he and a friend (unsure of this) decide to make a list of things the protag should do before he died. A few of these things were to "kiss a girl" or "smoke" or "slide down a hill of snow on a sled" and other things like that. The father of the protag didn't want to get close to him because he knew his son was going to die, but in the end they interact more and bonding over sledding. The protagonist even tells his dad about his list and what he did (smoke, etc.) and the dad doesn't get mad or anything. The protag does manage to do all the things on his list if I remember correctly. The book ends with the protagonist falling asleep after a nice day with his family and he passes away, but not before he views his sleeping parents through astral projection. It was a real tear jerker, actually.

The name of the main character was something like Lucas, or Michael, or Jack. I would be very grateful if someone could help me find this book.

[[EDIT: Thanks to Courtney I was able to find the book I was searching for. It is called "Ways to Live Forever" by Sally Nicholls.]]
