I like to play solo as well. Just for the challenge mostly, you know completing activities that are supposed to require a team. Part of it is the fact that I just want to relax and shoot aliens or other guardians in the face (one of the few games that I like PvP and PvE in equal measures) However I don't have the anxiety issues, I enjoy playing this game with my friends IRL and my gaming friends.... It's just so difficult to find enough of them online to do the larger team activities!
