I've feel that way when I'm in the throes of depression or in codie overdrive. Of course I didn't think I'd miss myself - I didn't have any "self" left to miss! I'd given it all to AH, my parents, my friends, my coworkers, my job, whatever.
I'm sitting alone in my house right now; AH is away on a business trip all week. Yeah, I feel kinda lonely, but it's not the type where I feel there's not a soul on earth who wouldn't miss me. Just kind of a case of the Sunday afternoon blah's. This, too, shall pass. But I do empathize with what you're feeling. When I get that way (and thankfully it happens a lot less than it once did!), I go to the mall and "people watch" or I put in a comedy DVD. Sometimes just getting my mind off me helps.
