Not really. Psychology problems are mostly found on your behavior. Things like the way you talk, the way you sit, the way you look, etc. can't be evaluated online.
There are some other interesting psychology tests that you might find online. Like to find out if you're introverted or extroverted and to find out if your a type of person classified as thinking, feeling, intuition, and/or sensation.
Or umm maybe you could find lists of psychological problems and look at the symptoms to see if any of them fit to you. Or not. There is actually a syndrome which I forgot the name for people who spend countless hours online looking for problems on themselves.
