Give us some more info to help. I guess we can send some e-empathy your way (wasn't trying to be e-sarcastic hah).
Were you waitlisted anywhere? Are you still in undergrad taking classes or have you graduated? How good of quality in various settings have you accumulated?
Do you have any volunteer experiences?
If you're still in school try to finish our with as high of GPA so that way you can show improvement if worse comes to worse. Try to get to 3.3 or perhaps 3.5. I'll let you figure the rest I implied.
