All Friends help my family

Respected Sir/Madam,
I'm writing this in hopes that you will help me in this matter. Myself Khondoker Faisal Aziz Mehedi, a 38 years old man from Bangladesh. I entered Singapore in 2014 with the debt of nearly 8000 SGD and with hopes of better living with my earnings . However, it seems like my hopes of a better living with my family has become a dream and my struggles have no means to end. Just a year after I entered Singapore my 70 years old father meet an accident in which one of his leg got damaged and operation was required. Consequently, unwantedly my family had borrow money again. Though the pressure of debt increased but my father is now able to walk with a support. As his son when I should have been the only support of him at his this age, my support is not yet enough. Hence, beside my work I had to look for other means of incomes and decided to use my knowledge on computer repairing. But it is really unfortunate for me as a son that even my all day and night hard works is not enough for my old parents. At present my salary is 700 SGD and with some computer repairing work I can highly earn around 200 SGD depending on work . So all together I can highly earn around 900 SGD depending on computer repairing works . From which I keep 200-300 SGD as my personal expenses and I sent the rest to my family. Among which I can hardly send 250-350 SGD for debts and with the remaining 150-250 SGD my family has to live a hard life struggling with the basic necessities . From my struggling life I have understood if life does not want to show mercy no matter how hard you work, how strong your will is but nothing is enough. Hence, I'm writing to you with the hope of your support along with the hope that life will show some mercy to me and my old parents. Though it is around 4 years I'm using my knowledge on computer repairing but as I don't have a fixed place or anything like that through which people will be able to know that I can assist them, my work is limited within less amount of people . I want to use my knowledge in large scale providing furthermore technology related services. But as I said our will and hard works can't see light unless the life agrees to show mercy. My knowledge needs financial support and as I'm already in debt I can't bear it more. Sharing my problems with one of my friend has informed me about you. Hence, I'm writing with a hope of your kind support . With your little support I can use my knowledge in an appropriate manner, support the living of my old parents and get out of the debt which has become a burden on happiness and smooth living of my old parents.
Therefore, I would humbly request you to support my knowledge so that I can give my old parents a better living.
Thank you
