Diagnosing over the Internet from one post is relatively bad. Some of the things you mentioned, such as eye-contact is not always a pathological symptom. It usually indicates low self-esteem but that is not a disorder. It can be a symptom for numerous things or nothing at all.

For the rest, they can be symptoms but you need to meet a diagnostic criteria. The quizzes on here are not diagnostic tools, so don't take a result from them as indicating that you may have something. If anything, take them with the notion that if something is bothering you quite a bit, then this quiz will obviously reflect that and indicate the severity of you going to see someone for it.
