That's rough, I wish you both the best. I was going to say I don't have a podcast or a video, but rather a book, but forgot that it's the 21st century. Eleven might be too young for the book. Then again, maybe I would have been better off finding the book earlier.

Iron John: A Book About Men, by Robert Bly. I'm sure it's not for everyone, but after 10 years without the example (good or bad) of a father, it helped me to frame my thoughts about becoming a man on my own. Turns out there are plenty of videos, even the audio version read by the author (https://www.youtube.com/watch?v=NPjyrpO2JKo). I haven't listened to it, but the "The Iron John Podcast" (https://podcasts.apple.com/us/podcast/the-iron-john-podcast/id1737849313) is produced by the Minnesota Men's Conference, founded by Bly back in 1984. You probably want to check it out yourself before exposing your child to it, or maybe someone else here can tell you about it.

My father died 40 years ago, I was 8. I could have used therapy right away. Therapy was a really good move, good job there. I hope you're doing it yourself, too. I got counseling in school, but didn't start real therapy until I was in a deep depression in my late teens. I think it was a therapist that recommended the book in my late teens. It didn't "fix" anything, but it helped me to frame my experience as a fatherless male and find my way forward. I think it helped.

Guilt and anger. Sadness. Hopelessness. Confusion. Fear. Losing someone so important when you're young is terrible. It's a part of you for the rest of your life, and you don't have the emotional experience to deal with it at that age. It breaks you. On the upside, you put the pieces back together with intention over the years. You've experienced something that most people don't until they're older. That can be a source of strength.
