Hello - advice sought re legal assistance

Hi Steve 
Sadly there are no law centres on this list in Scotland. The trouble for me has been exacerbated by the fact my issue is from when I resided in England, but I now reside in Scotland ... and then there is the huge amount of time that's passed (16 years!) on top of my sight impairment which has been worsening since the issue arose. I need a family lawyer with knowledge of both Scots and English law who can assist with getting me advocacy/admin support at home - previous lawyers have not adhered to reasonable adjustment re font size and preferred communication, and have charged me a fortune without bill itemisation for their time, which due to my poor eyesight meant I needed many more calls than most people. I now struggle just to find paperwork that's been poorly filed over 16 years and after 2 house moves last year. I cannot see any way forward as I now live in a rural part of Scotland and feel I will die before this divorce is finally sorted out. My mental health is currently suffering as I'm receiving quite threatening letters from the court in Reading, England, and the ex's solicitor which I cannot adequately respond to - a fully sighted person would struggle with the ridiculous Schedule E form plus 16 years of paperwork with which to calculate income and expenditure. I also must endure eye injections every month which ironically are currently performed in London as I cannot, as yet, access this healthcare in Scotland. 

I am utterly exhausted.

Thanks for trying to help.

Best wishes

Thanks, Steve, this is helpful. Any further digging on the internet would be greatly appreciated too.
