Inferiority Complex due to short height.

I have been facing this issue since I was in class 8. I wanted to grow taller but couldn't. Each and everyday I saw my classmates towering over me and I felt inferior. It has reached such a level that I am not able to stand near a six feet tall man. I feel jealous I feel inferior and I can't take it anymore. I want to die because I can't change this height anymore. It has reached such a level that it is on my mind 24/7 I always be with my friends so as to forget about this problem but as soon as I am alone I am so much depressed that I couldn't even study. I want a solution of this problem. I've tried every possible way of eradicating this problem but I can't help it. It keeps coming back to me as a nightmare.
