Hello,
Sorry to hear about your tough medical issues that have hurt your GPA. That said, you can still do a number of things to get into a decent MBA program (not the top programs with your profile, but you know that already)
What are you doing for work, or have you not worked before? Have you started thinking about your personal stories, essay topics, what your application strategy will be? With your profile, it is very important to have the right messaging come across in your application to offset the grades and the GPA. Given your reaction to your GMAT, I take it you cannot improve that at all, correct?
Contact me separately for additional guidance or if you seek some in depth professional coaching. My guidance that I can provide here is to think about how you will address your young age and lack of work experience, and have your GPA story concise and consistent, since you should mention it in the optional essays. That said, you can still have a good shot if you put together a solid application. Good luck and I look forward to hearing from you once you browse my site if you are interested in talking in more detail.
