Well, none of us here are capable of diagnosing anyone.
The things, you mention may be related to aspergers, - or it may not.
How were you as a kid? What do you remember? Do you have anyone to ask? How was school?
You could, initially, read a book by Tony Attwood.
The large one: "The complete guide to aspergers syndrome" is very thorough, but very child-focused and has lots of inner descriptions.
I would think, that the smaller one, "Aspergers syndrome - a guide for parents and professionals" is easier to read first, and it has a splendid foreword.
See, what you recognize, - perhaps write it down in order to get an overview.
Perhaps you could ask your doctor, what he thinks?
If you do online tests, - do the same tests once a month for three months and make an average.
Online tests is NOT a valid diagnostic tool, but done systematically and thorough over some time, they may give a hint, - and only maybe.
