You should be able to see your own deleted posts.
(You should have received the comment in your Inbox, as well.)
You may potentially have to refresh the page to clear the "This post has been deleted." banner, and see your deleted post in a pinkish background shading, probably near the bottom of the page.
Deleted answers should always be visible to you just by visiting the question's page (and, as noted, possibly refreshing the page).
Irrelevant to you, but in the interest of completeness:
Deleted questions can be seen if you have a link to them. Recently deleted questions can be found via your Profile page, on the "Activity" tab, under "questions" — there is a link at the bottom which says "deleted recent questions" and (huge shocker here) gives links to any recently deleted questions you've posted.
