I think that only you have the answer to that question. College is an opportunity to branch out and step out of your comfort zone but, no one is going to force you to do so. If you are asking for my advice then, yes, I think you should try to branch out and push yourself outside of your comfort zone.
One facet of your college tenure is totally unique: the time you spend in college is the only period during which you will be entirely surrounded by people roughly your age with similar goals and aspiration and, yet, come from a variety of different backgrounds. My recommendation is that you try to share at least one moment with a stranger each day. It could be a brief conversation while waiting in line to get coffee or a meal or simply a nod and a smile. Doing so will make it easier to interact and connect with people and the world around you. It's something you can carry with you into post-graduate life.
An open mound is a powerful tool. This exercise will help build that characteristic.
I hope this helps - good luck.
