I was in the solo commercial cross country for ZZZ1-ZZZ-ZZZ1 and before arriving the ZZZ. I wanted to go to the bathroom quickly. Usually; I do touch and go but I did a full-stop in the airport. After been to the restroom; I realized that I was too late for the schedule once making a call to Dispatcher. The Tower told me that wind [was] 290 at 12; cleared for takeoff. I put in the left aileron and right rudder with rotate speed 55 and when I started flying; the aircraft loses lift and divert into the left side of runway on the grass. No visible damage on the airplane.
PA-28 pilot reported losing lift during takeoff and ran off the runway onto the grass.
