I am dying due to hidden terms of your killer bank

In 2014 I had encountered serious personal challenges including the beginning of the fall of my marriage. As a single parent that was not supported by my husband I approached the bank for support as my children were put out of school for non-payment of school fees for almost 2 months. I was renting a place while trying to put food on the table for 4 kids. The person that assisted me in May 2014 at the branch never indicated that by taking the loan I am in fact signing a death sentence as since I started repaying an amount of almost R4500.00 each month - after 15 months I have no reason to believe that the bank actually helped me. I moved out of the house as my salary cannot afford to rent and took my children to another town where they now live without me as I cannot afford to take care of them daily. I also so badly app**** for a home loan and due to this ridiculous repayment I feel that there is no way out. The repayment term is 65 months which is not what was clarified to me. Yes the documents were signed however my state of mind was not right as I know that I shared my plight with the man that assisted me. I am unable to get a home loan and it kills me....I cant take it anymore
