Consider getting a part-time job or volunteer position where you are interacting with people. Think about your choice of activities and clubs – some involve more interaction with people than others. If you are “going days without talking to anyone,” then the clubs you have chosen are not the kind that provide regular interaction that can lead to friendships fairly quickly. See if you can find some clubs, sports or other activities that have you around the same small group of people very regularly, and require talking to each other as part of the usual participation. Try striking up conversations with people you encounter in your daily life, even if they are not people you think you would become friends with – it will help you feel less lonely to simply have some conversations as your day goes on. Carry on conversations online or in texts with your old friends and family members, so you can share your day with other people in at least some small way. Attend events and look for other lonely-looking people who might appreciate you talking to them. At a university of that size, there are likely thousands or certainly hundreds of other students like you who are eager to make new friends, and not knowing quite how to do it. Give the process some time. Accept that shy people can take longer to make friends, but eventually it will happen. Try to stay positive and confident. Don’t isolate yourself home alone, but rather find excuses to go be around other people. Study at a coffee shop or library instead of in your room, for example.
