Back off a bit: Reduce the intensity of your exercise by to about 80% of your current effort. Once you improve your strength you may gradually increase the rigor of exercise. Have a healthy diet, drink plenty of water, have safe sex if you do, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV vaccine. Wish you good health!
