Please help me.

I Am 18 F mandatory to mention age and gender as it plays an imp factor for what i m gonna ask .

My father’s height is 5’11 My mother’s height is 5’4. Then why am I 5’1 ?

This is not done😭

I was 4’9 at the age of 12 when i got my first Menstrual period .

I read majority role is genetics . Then other factors are exercise and nutrition .
Yes i was that child . Still i am who does not eat vegetables .. but we used to play outdoor games everyday in school till 9th (15yrs )

Till 10th i didn’t notice all of this . I didn’t know this would happen to me .only if i had known all of these before ..i was so busy in study for boards for 10th and then 12th .. i forgot my physical health .( school to tuition to self study ) And now this is my 1st drop ( preparing for NEET )

I also thought of taking supplements a year ago if i have some nutrient deficiency . My parents won’t allow for that . They say there might be side effects .

What can i do now ?? even if i could grow 2 -3 more inches . Please tell me what to do ??

Though i want this but still i feel bad when friends relatives mock at me .
