It would be better if someone can tell me a way through which I can find the post by myself rather than being completely dependent on moderators or the Stack Exchange team. Any suggestions?
In general, to find the comments you have posted without someone else randomly linking you to them, you can follow these easy steps:
- Go to your profile
- Click on the "Activity" tab
- Click on "All actions"
- Click on "Comments"
This list is organized by most to least recent. So if you know approximately when you made the comment, it should be easy to find. Otherwise, if you have a lot of comments, you might have to use the SE Data Explorer as indicated by Glorfindel.
It should be noted that this list does not show comments on deleted posts. Additionally, comments are by their very nature only temporary. If a comment does not show up on the list, consider the very real possibility that it no longer exists.
Assuming I've found the correct account, this page in your profile shows all your comments. They are in chronological order so if you know roughly when you posted the comment it should be easy to find. I don't think there is any way to search the list of comments.
