Oh Riley,
You sound just like my internal speech, except flip genders.
You are the son as well, and some day, your parents will realize this. But first, you need to realize you can do something about it, and are willing to go through sacrifice and struggles alongside your brother and the ready of your family.
Hang on there, given time, which we are oh so impatient through, and this too, shall become reality. Your fate is in your own hands.
