What can I do to not go bonkers?
On a slightly different tack from the recreational ideas, have you thought about volunteer opportunities?
Depending on your talents and interests, you may find a "fit" with some local organization that needs your help in helping others.
Aside from the help you are providing, you may find it a good way to get to know other local folks, them to get to know you, and for you to feel more a part of the local community.
