Considering that every individual human being on this planet has different social desires... yeah, no. A lot of people worry about being alone because it's a legitimate fear. No one wants to be truly alone. One of my coworkers has not had a date in 5 years and he's probably the most depressed person I've ever met for exactly this reason.
Me, I'm also worried about living my life alone, which why I'm very glad I do have someone to share it with.
