I can sympathise with you probably more than most on this board, anotherbrick. I also have aspergers syndrome. For those who don't know what it is, it's mainly a lack of social skills. They learn social skills intellectually rather that intuitively. Mentally there is nothing unusual. People with aspergers syndrome are often of above average intelligence and often excel in their career. Albert Einstein himself had aspergers as well as Isaac Newton. They also have a primary area of interest, and they tend to become obsessed with this interest to the extent they often excel in it. Mine happens to be I.T (I work as an I.T technician as well). The reason for this is because it replaces interaction with other people as interaction is difficult for us. Other common "primary areas of interest" include music and science. None of them involve socialising.
As for the mission, I did serve one, but came home after 10 months. I served a service mission, but, as is a common trait with aspergers, I had difficultly accepting rules that I didn't agree with. It didn't cause much of a problem with other people and certainly no arguments, but it bothered me to the extent that ended up coming home. Plus I have difficultly with the idea of being banned from anything to do with technology due it being my "primary area of interest" (see above), I struggled with this more than a so called "normal" person would. Do I get discriminated against? Of course. But I don't really care that much about it either though. People don't understand the condition until they have had it. People say I am addicted to computers and technology which is why I ended up coming home... the symptoms are very similar, yes, but it's not an addiction. You can overcome an addiction, you cannot overcome aspergers syndrome. Plus, due to my so called "addiction" I now have a job which I really enjoy and effectively get paid to do what I enjoy doing. So it's not entirely a bad thing. People at church also come to me to fix their home computers and sometimes I get more money out of it if they insist on paying me (I usually don't accept payment).
So make the most of what you have and stop worrying about what you don't.
