Well love does make you feel pathetic but that doesn't mean you are. I think this is just an uncomfortable situation your in. Nobody likes to be confused and that makes us feel pathetic becuase we feel that others arent confused and are constantly judging us. Which perhaos we are but were all pathetic when it comes to this sort of thing. What i mean to say is even if you feel helpless your not you've just got to deal with this problem head on.

Just try being friends with her first, and dont just give up if you care for someone like that. Its hard loving someone but having them not loving you back. So you might just have to accept that she doen't feel the same way. But if you care about her enoguh then you'll do something about it and take action. If you dont love her and just have a crush on her then you might no take action. The right person will find you im sure of it dont worry.
