Advice for new girl in Lincoln?

I just moved here a couple weeks ago, got a place downtown, and am going to start at UNL in August. Is there anything I need to know about being downtown? Places to avoid? What are some fun things to do to in that area? I'm from somewhere pretty small and very far away, so downtown Lincoln is a little bit intimidating for me. I don't really know where to start! Any suggestions or advice would be greatly appreciated. Thanks in advance :)
