Please help me get into Grad school

Hi, my name is Yanique and I am working towards getting my doctorate in Occupational Therapy (OT). My brother was born premature and needed occupational therapy services. That's when I was exposed to OT and I fell in love. And my brother is a living testament on how OT can affect a person's life and I dream to do so also. 
I Finished my undergrad as a biology major in May 2017 and I am ready for the next step; graduate school. Last year 2018 I started my application but was not able to send it in due to funds. I was not able to cover my application fees. This year I started my application and I bumped into the same problem. I refuse to let this hinder me from continuing  my dreams and changing lives around me.
I've been thinking how there are so many people that wants to better themselves, their family, and the world around them but they haven't gotten the chance because there is something that is hindering them to do so. But I believe in a God and I know once you put him first nothing is impossible and everything your hearts desire you will receive  it, God's willing.
If you can help me I will really greatly appreciate it and I know God will surely bless you. Thank you
