Fund raise for little brother ADHD medication

This is my little brother Muhammad, he's got ADHD since he was a toddler, his speech abilities are still basic compared to his age, 9 years old, and he started going to school this year, his cognitive skills are also at a declined level compared to other children at his age, the problem is that we can barely afford his medications which are as prescribed:

Strattera 25mg, 30 pills per month / 1 per day
Abilify Syrup (Aripiprazole) 10mg / 1 spoon per day
Clonidine (Catapressan) / Quarter tablet per day
His medication costs us $250-$300 per month

Rx can be found below:

We're a family of 5.
The requested fund is enough to supply the medication for 3 years.

After my father passed away two years ago, my brother started having ticks and issues with his muscles, and also his self-awareness level has declined as well, I work as a full-time web designer and earn $400 a month.
And my mother receives a retirement salary of my passed away father, which is about $660 every 2 months.

I'm doing this fund cause my mom's health isn't very well, and she can't work, my old sister is unemployed and my little sister is still a student.

Thank you a lot, and God bless you...
