How to re-add a deleted friend on facebook?

[Louise]

I removed my sister as a friend on facebook a while ago because she was annoying me and facebook stalking my wall. Now I'm moving to uni and want to add her again, but can't 'find' her profile by any of the normal searches- not even by going to mutual friends' pages and looking there. Same her end- she can't find my profile either. Is there no way I can re-add her?

Search them!

If you know her email address, you can try searching her on facebook with that, otherwise, you could contact facebook and explain your situation and I'm sure they'll be glad to help you out.

If you had each other blocked at some point, then of course, you'll have to unblock each other in order to add again. You can unblock by going to "privacy" settings and clicking the blue "remove" button.
