A candle loses nothing if it is used to light another one

While cleaning the house, I saw a piece of paper in my closet. Out of curiosity I read what in it and found this verse," A candle loses nothing if it is used to light another one". Then I remembered one event in my life that contradicts this verse. Before I left the Philippines, I have a lot of loans,  left and right, to public and private companies and individuals because during that time, the construction of my simple house is going on. So in order to finish my house faster, I loan money with interest from one of my friends( at least I count her as friend), and I promised her to pay back monthly. I really worked hard those days, almost 16 hours a day just to pay back all my loans. After a month, I paid half of my loan to this person and promised her again to pay back the remaining balance in installment basis monthly. Then next payment day, I wasn´t able to get the money intended for paying my loan because my tutee whom I will get the money was in vacation. Then my lendee came to me to get the money. I told her what happened that I can´t pay her back that day. Instead of understanding my situation , she gave me insulting words and blaming me of many things. She humiliated me that hurt my feelings so much. To end my conversation to her(and I don´t want to talk to her anymore that time because I felt bad and wanted to cry) I told her that I never run away from my debts and I know how to pay my loans. I promised her again to pay her on payday.   And that´s what I did. As I received my salary, I asked one of my friends to give her the money back with interest. I gave her all my remaining money and nothing left for my family that time. Since then , I didn´t borrow anymore from her. Next day, I found out that it was only me whom she insulted among her lenders aside the facts that some of the other borrowers didn´t pay her too. That incident forced me to come to Europe to earn bigger money so that my way of living upgraded and I will never experienced that situation again. Because in this world, there are people who used their money to insult other people especially the needy like me. Some of them use such situation to humiliate and to hurts someone feeling. They act indefferent to penniless people. Instead of helping the borrowers, they buried them or us with big interests that we could not able to pay them at once. As I evaluate what happen, this person didn´t help me anyway that time, she added more burdens on me paying her money back with big interest. Shame on her for having such attitude.
Now I am here in Europe. Some friends borrowed money from me and I lent them without interests. If they don´t have money yet to pay back, I never forced them nor tell bad words against them because I understand their situations. I know how they feel because once I was a borrower. I know that they borrowed money because they are really in needs. I want to lit their candles and not to be an added burden to them. How I wish and I pray to get more jobs so that I can earn money. I am planning to save some of my friends in the Philippines who are buried with great loans to her or to these people by lending them money  in order to pay back their loans and lighten up their burdens. How I wish I can light their candles, and give them hope.
