HELP ME FOR CONTINUING MY HIGHER STUDY

I live in Bangladesh which is a third economic country of southern Asia. Recently I have completed my B.Sc. Engg. in Electrical and Electronic Engineering from a public university named Bangabandhu Sheikh Mujibur Rahman Science and Technology University, Bangladesh .I have completed the degree with the highest CGPA in my class with result 3.81(4.00). Now, I am planning for higher study in Masters or PhD in my sector in America. As a member of a poor family I have managed for taking the GRE test with my own tuition savings and now preparing for IELTS test. As in my country there is a great scarcity of part time job and govt jobs, so it is very tough for myself to manage the test fee and applications fees, GRE and IELTS result sending fees in the universities in abroad as the scope of higher study in my country is too small and research option is very limited. There is also the pressure of maintaining the family cost is now depends on me but my little tuition saving is not enough for my study but what about the family? So it is very pathetic for me to carry on with my dream to be a good researcher and maintain the family. In this moment I can't even think what could I do, then I came to learn about this site and the worldwide best donors are so helpful and now I am applying for help. I even don't know what will be the response and can't express my situation as the financial problem I am facing now. So please help me and I will be so grateful to you all...
