Nothing is wrong with you. I remember when I felt like this. I was convinced nobody was going to stick around forever, and that it was my fault somehow. It was a wait, but I've found a lot of people since then who will always be with me. Keep pushing forward, be your genuine self, and you'll find those perfect people.

Friends you meet when you're a teen will never stay no matter what. When you start in a job with people closer to your age is when you really start making real friends. We all feel unloved. Remember that you deserve love and happiness.

Idk, I have a couple friends from high school that I know aren't going anywhere. My closest friend(so close, we just refer to eachother as brothers. We call eachother's moms Mom), I met him when we were both 5 or 6, and we were brothers by the time we were 13. My best friend, Kate, I just met her less than a year ago. I've been in a bad place and tried pushing her away on more than a few occasions, and she's still here for me. It doesn't matter when you meet a friend. If they're a real friend, they'll stick with you for life.
