Your domain is worth whatever anyone is willing to pay for it.
But here are some factors:
Determining The Value of Your Domain Names: iGoldrush Domain Guide
Note this one:
G) Does the domain name resort to prefixes or suffixes?
Prefixes or suffixes can REALLY hurt the value of a domain name. For example, add an "e" or "i" or "my" [or "your"] in front of the domain, or a "site" behind it and you’ve just destroyed most of its value. (Exceptions exist of course, such as EBay.com which is worth millions of times Bay.com, but that is because of the tens of millions of dollars poured into branding the domain name. Seen totally independently of the site/service it relates to, eBay.com is worth much less than Bay.com)
You've got a "your" in front and a "site" behind - I'd say, without trying to hurt your feelings, that the domain name itself is worth very little beyond the registration fee.
