You can get involved with sports, do charity work, sign up for clubs, just do something that makes you look at life through another's eyes. Sometimes you may need a breather, but don't cut yourself off completely from friends. And the only way you can make new friends is to make an effort. Friends are who make hard days easier. Friends are the people who make late night study sessions worth the effort.
Friends are what make the college experience worthwhile.
Your life is up to you. You either learn how to swim, sink or stay on the shore, watching everyone else having fun.
