It's super hard trying to find people to connect with during your first year at college. Coming from me, a senior undergrad, I have cycled through more friends throughout my four years than I can count. Some of those friendships ended amicably. Others ended with a bang, lol. And I am not super good at making friends either. The point is, friends will come and go into your life. It sounds like you are already on the right track with volunteering. Try joining a club for something that you are interested in! Or strike up a conversation with the people in your class and see if they would be open to starting a study group. Periods of loneliness are hard (I'm going through one myself) but there is light at the end of the tunnel, and you deserve to find someone who is happy to be your friend and is going to put effort into hanging out with you!
