Set your 'showdead' to on in your profile page and go back to look at your comments. They'll show [dead] next to them. Alternatively log out and see if your comments are still visible.

That won't tell you if you are dead though. I think that is what OP was asking.

Actually it does show your own comments as [dead]. Or at least it did for me a month or two ago when I tried it. It's how I found out I was dead.

Interesting. My comment was made after reading through other posts in this thread. I always thought "dead" just meant heavily downvoted comments.
