I had few friends in HS I move around a lot. You make better friends in university, and even if you don't make too many friends in university, you learn to make friends as an adult. Also friends can sometimes mean drama. As you age, you'll learn to appreciate yourself and a quiet life. You can dedicate your life to work and material possessions. You can dedicate your life to your family, and raise your children without distractions. You can dedicate your life to your community, volunteer work, fundraising, activism, politics, college instructor etc. There's so much you can do or be when you don't have friends or have few friends. Don't be sad, just have the confidence to do the things you want to by yourself.
