Help me go back to school

My name is Kathleen, I am a single mother raising my kid all by myself. I am currently 8 months clean and sober.  Before I had my child I was homeless living under a bridge with drug addiction. Now over 3 years later I had a spiritual awakening and turned my life around. I finally got an apartment for me and my child. But I am stuck with a bill that is threatening to go to collections. After I pay my other bills like rent, and electricity I'm really not left with much left over to pay my student loan. I want to finish college and get out of poverty but I am struggling. Thank you for taking the time to read this. Have a blessed day.
