It is likely that you have achieved your adult height. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV and Covid vaccines. Wish you good health!

If you have only grown an inch in the past 5 years you are at the end of growing taller. Expected final height is the average of both parents plus 2.5". More growth requires open growth centers in long bones, which can be checked in a single x-ray of your wrist/hand. If open you will grow more, closed you are done.
