I figured out quite awhile ago how to be your own friend.
1. Log into Stardoll (it works better if you have had your account for atleast a week)
2. In the search your friends box search something that is impossible to have a name as (like $$$)
3. Then when it comes to the page where it says they can't find anyone named that, delte the impossible name you put in and put in your own username
4. Click the request as friend button and send a request!
5. sometimes this might take atleast a day till you come up in your unclassifed area on your friends page (I don't think you have to accpet your request either)
PS: please tell me if you need help or don't understand.
