I cannot relate at all. I've had difficulty making friends since I was a kid, because I was really socially awkward. I always felt like a loser. I especially had a lot of difficulty making friends with girls, as I felt like they thought I was weird or creepy, that they didn't want anything to do with me. I found it a bit easier during high school, but college was truly some of my loneliest days. I recall taking courses with a small-knit group of about 25 students in third year, and not a single person talked to me or even really said hi. I felt so invisible, so worthless. I honestly felt like I didn't belong in the world, and I cried all the time after class when I was by myself at home. I escaped through video games; it was not really a healthy obsession.
As an adult, it's still hard. I've still never really overcome the idea that "nobody likes me", "I'm a loser", "I am unlikable/unlovable". It feels like something is absolutely wrong with me compared to someone like you who seemed to have an easy time making friends. I just didn't have that same kind of confidence as you.
