Katie, There is nothing wrong about being bored and being by yourself.  It’s a great opportunity to BE with yourself.  Consider this as a meditation.  Are you meditating?  This will help with your nervousness as well.

Are you more interested in doing social activities with others or to be able to talk with a good friend to help process your breakup?

This is a great forum to do the latter.

Socially there are social groups around like Meetup or try reaching out to do something with one of your friends.

Let us know what you want and how you are doing.
