xml not readable –

Since a post on April 2, my rss feed has not been working. It won’t validate.

Feedburner says: The URL does not appear to reference a valid XML file. We encountered the following problem: Error on line 68: The element type “category” must be terminated by the matching end-tag “</category>”.

Feed Validator says: line 68, column 5: XML parsing error: <unknown>:68:5: mismatched tag
Line 68 — ]]></content:encoded>

Help???? I have NO idea what to do and I am frustrated because I don’t even know where else to search.
