Hi!
Your height to chest ratio is ideal which measured as 31 inches. Growth failure is a known cause with long term use of steroid therapy more so with dexona (which is a long acting steroid). However, your height potential also depends on the heights of your parents ([height of mother in inches + height of father in inches]/2) + 2.5 inches. You fall in the 40 to 50%ile range for an Indian male which is slightly below the average but not unhealthy or abnormal.
Usually, most boys stop growing by the age of 16-18, so if anything you might have lost an inch or half in height.
There can be other reasons affecting your stature if your parent's height is more than yours.
However, there is need for some counseling here and I will suggest you to seek a consultation.
Next Steps
There is no need to be embarrassed or ashamed of your stature. Your stature is not abnormal.
