I would suggest you focus on other parts of your application: GMAT , essays, recommendation letters, resume etc. An excellent GMAT score, great recommendation letters, perfect resume, and effective and persuasive essays can always offset your poor GPA. Also, you have a valid reason to explain your low GPA which you can very well do in your optional essay.
Right now , aim for a stellar GMAT score and work hard for it.
I hope it helped.
