I need a financial assistance and help out of debt

Due to marriage broken up in 2014
I'm in debt with outstanding balance of £18226.50 which is affecting my health and my family 

In 2009, I have already spent balance of £7877.62 from Barclay bank credit card to renovate our family house in other to inrease rhe value of the property.
So that we could sell ourselves if our marriage doesn't work.

In 2012, After I finished the renovation I was sent me out of our family house by ex-wife.

 In 2017, Our family house was finally reprocessed by Halifax and sell it. 
The arrears on our house after the Halifax sold the house which remain the balance of £10348.88 which has affected my credit rating since then since then.

I got four kids, three boys and one girl.
Two in the university in London one has just graduated 
My youngest one is in high school 

I do private hire taxi driver 
On the 25th of March I had a serious accident with my car the only source of income to feed and support my children 
My Insurance couldn't fix my car because my premium is third party 

My landlord too was threatening that he want me out of his house, as he want to sell his property.
There no place to go easily with bad credit rating 
My daughter was always in a bad mood and feeling for me because of my financial situation
