Dad needing help with Divorce Costs

Dad of one needing help with Divorce Costs as wife has decided to take matters to court even though neither party can afford to and initial suggestion to deal with this privately to avoid Sol's and court costs was thrown out.

Wife is attempting to take everything leaving me with nothing including controlling access with my son despite me trying to spend time with him.

I invested heavily into the property and mortgage as well as her business and supporting her family.

Divorce costs are running into thousands which I cannot afford and am unable to get legal aid to help. My sum income is £26k so on top of mortgage payments and bills I have now run out of any money to pay for my Sol's (£250/hr) and eventually barrister (£1500/hr) for court.

My family are unable to help out and I have no savings as I invested what I had into our house and wedding.
