I just need some advice and honesty..

Are there any adults on here who have never friends? Like, even growing up? I'm an outgoing person and am engaged in activities with other people but I still don't have friends. I'm 17 and have never had friends. It's pretty pathetic. Everywhere I look, on this app, any social media app, and in real life, people seem to actually have people to talk to. They don't seemed trapped within themselves, dying for the least bit of platonic attention. I feel like.. I'm not normal. I literally have a boyfriend but no friends. What else can I do. I'm terrified of being alone for the rest of my life...
