If your asthma is not disqualifying and if your eyesight is correctable then there is a chance. I had a 2.4 GPA in Business as I to did not apply myself either. Joined the Marine PLC program, got a flight contract, kicked ass in flight school, selected jets and flew F/A-18s on the west coast. So if you have the desire and are willing to put forth the effort it can be done. I think your biggest issue will be the medical stuff. Good luck.
