Help me to finish university

Hi everybody. My name is Gleb. I want to tell you about my problem.  The technic attracted me from early childhood, especially computers. I could watch for hours people working at this incredible machine. Then I promised myself to develope my future life only to them I was always tought to follow  my dreams that time I didn’t knew that on the way to my dream would happen many troubles. Last five years I have been dealing with computers I like it very much and I cannot imagine my life without it. Following my dream I have been dealing with computers, I like it very much and I cannot imagine my life without it. Following my dream I have entered the best university in our state. But it cost very much money. My parents cannot help me because they have died in an accident for 3 years ago. I have only grandmother who is invalid. I was working at two places for 10 hours a day without any holidays and weekends. I came home very tired and continued to make my computer skill more perfect. Having worked for 1 year I earned 2000$ but it is not enough for my studying it costs 15000$. I am very hopeless. I don’t know what to do farther. You are my last hope.
