A quick question

A quick question What jobs require least interaction with people? I'm a student right now and I'll graduate in 2 years. I don't think I can build relationships with people. I'm incapable of that. Even if there is a chance of forming a healthy relationship, i would like to avoid it because I know that I can't maintain it and eventually it will be a disaster. So i would like to work in an environment where there are no people at all. But that's impossible because we ourselves cannot do all the work (if I'm wrong then I'd love to hear what such designations are there). Only because of this reason I have to have people with me. So if you know/are working at any jobs which require less people, please tell me. Thanks in advance.
