Your comment was not deleted, it was toggled by mistake. I undid the toggle (it wasn't originally toggled by me). It is now rated 1.16 with 6 retings awarded. It just needs two more members of the community to rate it with a zero and it will be hidden. Since you're not a trusted user you can't see hidden comments. To become a trusted user you need to write a large number of comments that the community rates highly.

If you stopped sowing discord you might increase your chances of becoming a trusted user.
