Help me buy a computer plz

Hey there! I am really ashamed of doing this for a personal purpose, but I don't know how other way I can afford the money to buy my own computer.... I am a 14 year old guy that lives in the state of New York and my family is at Colombia and I am in certain way alone..... It is really difficult for me to have to use computers from strangers or sometimes my school's computer and to hear my friends about playing games and all that...... I can't afford a computer with the money my family sends me.... So I am really thankful with the people that could help me about this.... a dollar is like gold for me and I am really pleased even if you give me 1 cent..... Thank you
