Hey demirs9, I completely agree with flyoneday "if you never go, you will never know" As far as I am aware, EK just want you to be within the healthy range with your BMI. Do your best to dig deep and give it a shot, because its times when you think you dont have a chance, that life proves you wrong and the next thing you know is that your packing your bags getting ready for your start date!!
Thank you to Mother Hen for your warm wishes as well
