I'm not sure... I think I'm usually ok at facial cues and especially voice intonation. Like for instance when someone says they're doing ok but you can tell that they're not by the tone of their voice. One weird thing I do experience although not that often is reading split second facial expressions like say when someone is talking as being threatening when it's not meant to be, but I think that's something different although I don't know for sure.
As far as my OCD like symptoms I would have to say they sound a bit different than yours. Rooms don't really bother me although I may prefer one layout over another but I think that is based more on ergonomics. Either way, here's a list off the top of my head of things I experience...
*Turning the knob on the washer and dryer 3 times sometimes more than once. Strangely I don't do this with door handles.
*Flattening the cat litter after cleaning the cat box out meticulously. Seriously, think cat box rock gardening.
*Sometimes paying attention to how many times I step on a crack on a sidewalk and making sure its more or less the same times on each foot.
*Tapping my fingernails together in sequences that are 3 times in 4 sequences or 4 times in 4 sequences.
*Scratching a legitimate itch on one side of say my arm, and then the other arm even tho it doesn't itch.
It seems like most of my things have to do with evenness... I guess that's sort what OCD is at least partly. I've also had intrusive thoughts pop into my head from seemingly no where like how I could do physical harm to some innocent person say standing in line at the grocery store or something like that although I of course would never do such a thing or would want to. Those only last about a second, and then I'm wondering where the hell that thought came from. I haven't had that for a while but the other things I have.
A lot of that actually sounds very familiar. I cannot use a desk unless everything is evenly distributed on it, I can't take more than one step on a side walk, and if I don't step on the cracks of a sidewalk when I first start to walk on it, I can't step on a crack at all, and vice versa. Scratching an itch on my body leads to me scratching every limb very thoroughly until it starts to hurt, regardless of whether I have an itch any where else. Or, at least this was the case before I started taking Adderall.
One thing that is also very familiar is feeling like I am going to do something violent, mainly kill, to people or animals next to me. It wasn't so much that I felt like I had to, it was that I felt like I was going to and there was nothing I could do about it. I would obsess over the image of me doing harm to them, and with each thought I felt like I was getting closer to doing it even though I wanted so badly not to. And briefly, for maybe half a second, after experiencing one of the thoughts I would think that I actually did it. I never actually did anything, but it made me feel absolutely horrible. I felt guilty, disgusting, and I was terrified that eventually I would actually do something to someone. It was absolutely horrible. Whether it is the same problem I don't know, as you have said you feel like you have to, and I felt like I was going to and it was out of my control.
IMO which is not a professional one, but one that understands OCD all too well, it does sound more like OCD than Aspergers. Everyone that I have known with Aspergers would not be capable of differentiating between someones actual emotion based on their tone of voice and facial expressions, but obviously, Autism just like every other mental disorder is on a continuum, and I'm sure there are more severe and less severe forms of Aspergers, just as Aspergers is a less severe form of Autism. Obviously, this is no way a diagnosis and the only true way to get one would be to go to a mental health professional, but even that can be a complete waste of time, so it is necessary to find one who really knows that they're doing.
My father is a PhD in psychology, and his estimate is that one in every five hundred therapists should be allowed to work as a therapist, and every one and a thousand psychiatrists should be allowed to go near a patient. Haha. He's worked in several institutions, and has worked as a therapist in several different places and eventually he dropped everything to pursue a career as a consultant because of how much he hated every place he worked as a therapist, and how much he hated the therapeutic model. At this point, he's even stopped acknowledging that he was ever a therapist because he's ashamed to say so. Of course, he said there are good therapists, and there are bad therapists, but the bad ones outweigh the good ones by a long shot. This is also just his opinion, but given the list of therapists and psychiatrists I have been to; I tend to agree with him. I'm just saying to make sure that the therapist and/or psychiatrists you see isn't a greedy douche bag.
Sorry for the long and unnecessary tangent.
Best of luck to you.
