Having no friends, or feeling as though you have no friends, is not uncommon. As we age, connections become harder to maintain, and we have fewer of them than when we were younger. It's common for this situation to lead to feelings of loneliness and isolation.
The easiest answer is to try and find some friends! This can be easier said than done. Especially as we get older, it can be hard to know where to meet people and find connections.
A couple of ideas for high schoolers are clubs and elective classes. After school activities are a great way to meet new people. Find out if your school has any clubs you might be interested in. Even academic clubs are a great way to get study partners, which can lead to friendships. Elective classes, such as art, choir, band, or a computer class, will put you near people who might share an interest in that class.
Advice for meeting people in college is the same, except that college is even easier! College usually has a lot more clubs and elective based classes where you can meet people. Because college classes are more difficult than high school, more people are trying to get together to study and share notes. And, of course, if you live on campus, you are surrounded by other people. Even if you don't live on campus, or are attending a community or technical college, your school probably has a place for students to hang out. Try spending some time there between classes. If you recognize someone from a class, go talk to them about the latest assignment!
Meeting people and making friends is all about being able to put yourself out there. It can be intimidating to talk to total strangers, but if you don't let that stop you, you can make new friends in no time! I like to ask a stranger a question about themselves right away. They're usually happy to tell me about themselves, and it helps me think of them as a potential friend, rather than a total stranger.
