How do you explain this?

My older brother was a pretty popular kid. The year I got to high school, he graduated. In 8th grade, I heard him having friends over, blaring music, screaming and having a good time. In high school, I would get text messages from people inviting me over to parties and saying it will be lit. I knew I couldn’t go because I don’t talk or hang out with anyone. I tried this one time and I got rejected from attending. I knew it was coming. I was never the type to get invited to parties or events. I wasn’t the popular kid or the cool kid. I was just the fat kid or the weird kid, which made me not popular. I got to the point where I stopped caring. I don’t do parties and I don’t have people I can hang out with. I don’t care for popular people and I don’t like people who think they’re popular. I like being alone and I’m good with that.<br><br>How do people have friends and a social life but also lack a love life?
