A Dentistry student single Mom

I am a single mom and a dentistry student as well. I have completely no source of income. My brother is the one paying for my studies but now he wants to start his own family. My father passed away 5yrs ago and from then on we had a difficult life. My brother is the only provider in our family. My mother is just a housewife, she has no source of income too. Dentistry is so hard and requires a lot of money. For patients and dental materials that we use. This is my dream. I really want to become a dentist someday and if I get to finish this I can help my family as well. I can provide good life for my daughter. Please help me to reach my dreams. I am so helpless 😭😥🙏 Please please. It would mean a lot to me if you could help me become a dentist someday 💕
