One of my big obsessions is letters, and the first letters of things in a list not being the same. So for example, one of my big interests is politics, but I feel like I can't really enjoy it properly because of the fact that Labour and the Liberal Democrats both have the letter "L" as their names. I want the names of all parties, and things in a list so have different starting letters, and sometimes I can feel physically a bit sick when this is not the case. Does anyone else have (or had in the past) any similar experiences, do you think this is Aspergers or something else (I also have OCD), and do you have any advice?
