Raise money for my sons with cancer of the bone

Good day,please i need you help.After my wife's pregnancy my son was diagnosed with cancer of the bone,after delivery we have been treating the sickness since then however it has only worsened mostly due to my lack of funds to take care of him since i lost my job at first bank due to the recession in Nigeria, the little money i make from selling recharge card i spend on school fees and trying to keep him healthy by buying drugs i can afford .Recently my son was rushed to the hospital as the sickness attacked severely he has been in the hospital ever since and i have no money to take care of him anymore the hospital refuses to let him go due to our previously large debt 800 thousand naira. please i am begging for whatever help you can offer my son cant die so early. The total cost of his treatment is 2.2million naira (5000 dollars) which includes the money owed i have been able to gather 250 thousand please help me by donating the rest.Thank you very much.
