Felix, You seriously need advice?  What sort of advice would you give yourself?

You feel that it is unfair that you have trauma which you attribute to the eating habit you acquired which in turn being shorter than the average height of males your age.

You stated this in your first sentence, that you have a hard time accepting your height.  What anyone says here cannot get you to accept who you are.  Only you can do that.  Men and women can tell you that your height is OK but will you believe them?  I suspect you won’t until you accept your self.  Are you willing to take steps towards that self acceptance?
