Body didn't grow. Of corticosteroid?

I'm 22 years old male, and currently facing PTSD because at the age of 18, I used 2 medicines which is practin and dexona, because an idiot pharmacist gave me to increase weight, and I didn't have that much time to research about it...so i took it for 4 month,2-2 tablets daily at morning and at night...i gained lot of wait and got stretch marks, and later i researched about it that it's corticosteroids, so i stop taking it slowly...but since that I didn't grow, i can understand about height, but my my torso is very very narrow like a modern girl, my waist is 27 inch only and also narrow chest(31 inch)and it looks like teenager's body, not like man, I feel shame walking outside, I had read somewhere that withdrawal of corticosteroid causes permanent stunt of growth, so is this the reason? My height also stop and horizontal growth too, and now I get very angry when i think about that medicines, so the main question is this happening because of corticosteroid?
