i can speak on this.....
i did a one yr smp previously and did not meet the gpa cutoff, ended up with a 2.87, mostly b's, a few a's and 2 c's.
at which point i thought i was in the same boat as you...i thought i was done.
so i made an appt with the ad counselor at the state med school who told me i should get my grad gpa up to 3.0, get back into volunteering (we had moved cross country so i had left my volunteer position and when we moved back we moved to a different area and i had not gotten back into volunteer work) and apply early early early.
so i spent a yr at a local state university as a grad student at large, got my grand gpa up to 3.0, got into more medically related volunteer work and began to pursue classes to get my emt-b at a local community college.
i applied to both md and do, and got no love from either.
HOWEVER, i was *extremely* fortunate to get into a second master program at mwu-il.
i have done exceedingly well in this program and am currently on the waitlist for ccom for the fall class.
whether or not i end up with an acceptance remains to be seen, but i think it can be done....
i would finish this year as strongly as possible (i believe gt is a 1 yr program??), and take the summer to talk to programs who will talk to you to figure out what you can do to best your chances at getting in.
i wish you the best of luck
