Long-term effects of bulimia?

I have been a bulimic for over two years and I am indecisive about whether or not I should get help. I would like to know about the long term and short term effects of this eating disorder. I would also like to know whether or not I can prevent these long term effects if I decide to quit in the near future because at this moment I have fourteen new cavities (which I'm currently getting fillings for) and one partially decayed tooth (which the dentist was barely able to save) and I have swollen salivary glands (which I hope are irreversible because they make me look like a chipmunk).
