It's not just you. It appears that Facebook is down or slow to load for many users.
The outage began around 9am EDT.
Both DownDetector and DownRightNow are reporting liely service disruptions and reports out outages.
Plus, users are complaining on Twitter, as they typically do.

We found that Facebook was slow to load if it loaded at all on desktop, but mobile seems to be working fine. We'll update accordingly.
