did this girl block me on facebook?

[Chris]

o, i used to have 142 friends, but today i went on facebook and i realized
that i only had 140. i scrolled down my friend list and i realized who was missing.
when i searched this person's name in the search bar, they came up, but apperently, their page was unavailable....
then i refresh the page and searched their name...they didnt come up....then i used another account and checked...she didnt come up...
then i searched all my friends who are friends with her but she didnt come up....

i then checked my messages, and this person was still there, but their name wasn't in a link-so i couldn't go to their page.
did this person block me? or did they just deactivate their account?
she might be mad at me but even if she was...it was something very little...
