Leave the fear behind and remember why you transferred. Most individuals who transfer from one college to another have a less than stellar experience at their first institution of choice. Being afraid to make new friends will only continue to hinder one's experience at a new university. The key to making friends is to get over the fear and not be afraid to do the work required to make new friends. Commit to meeting one new person a day for the first month or so at a new school.
Join an on-campus group to create a new social network. The quickest way to isolation on a college campus is not to take advantage of the extracurricular groups at school. Although many school organizations exist for a particular reason (philanthropy, volunteering, etc.) all of them can allow transfer students extra opportunities to make friends at a new school. By simply exposing yourself to more people, there is a greater likelihood that you will make more friends.
Cast a wider net in the search for friends and ask roommates, teachers and general acquaintances for help. While teachers and school officials can offer leads on unadvertised organizations, new roommates and acquaintances already have an established base of friends and can introduce a college transfer student to a host of new people. Piggyback on the social gains of those around you.
