I need some money for study

I’m 20 years old ,I study psychology but I couldn’t afford it anymore so I quit university, start working and saving some money for study , but I failed cause me and my brother take care of our family, we feed the family, we pay rent , we pay some debt in the bank , and pay some bills and it’s not enough for saving money . It is really my dream to go back to study and I love it so much and if you can help me right now I know that someday, somehow I will do the same for someone or someone will do the same for you . Thank you
