I am so sorry, honey. I've been there and it's a rough time. I'm glad you got to spend a few hours with her, though. I went through that with my mom at age 19. It's hard, but you'll get through. Your mom wouldn't want you to wallow and be miserable, but at the same time, if that's what you need to do, then do it. I come from an Irish/German family, and although funerals are not good times in general, we try to make them that way. We don't see it as a time to think on what could have been, but what WAS and make it a celebration of someone's life. You'll always remember what your mom was to you, and the good (and not so good) times you had. Hold tight to those memories, share them with your kids/family/friends, do for your kids what she did for you (even if they're grown), make her best recipes, sing her favorite holiday songs, and she will always be next to you. Sending you big hugs, and all my best wishes
Nan
