How can I see all my Youtube comments?
You can view all your YouTube comments by following these steps:

1. Click on the hamburger button (the three lines) in the top left of the page and click History.
2. Your YouTube history page will open. On the right-side menu, click Comments under Manage All History.
3. You’ll be redirected to your Comment History. All the YouTube comments you have made from your account will be listed here.

I hope this helps! Let me know if you have any other questions.
