I think this is pretty common, actually. Whether or not someone actually identifies as a submissive.

What you need to decide though, I think, is if that feeling does anything for you? Some people (not only submissives) get a certain satisfaction out of being a martyr. It may not be a popular thing, but it is something to recognize in yourself if you do... and to decide if you want to continue it, or if you want to change it. Having that martyrdom need fulfilled may be important to you. Or it may be a part of your personality that you don't like. *shrug*

I'm on the fence about this need in myself. On the one hand, I like being able to say, "This place would never run without me, I do EVERYTHING!" but on the other hand, sometimes I'd really like to take a fucking break! LOL
