Disability and capital gains

Hi,
In 2007 I had to sell my business due to a consultant at a hospital saying I needed both my legs amputated. My accountant said I’d have to reinvest in another business within 18 months or I’d have to pay capital gains tax. After the 18 months was up I’d still not had the amputation and despite complaining to HMRC that it was impossible for me to start a new business with a double amputation hanging over my head I had to pay up. I feel aggrieved at this especially as I’d saved all my life knowing the amputation would happen someday. I paid this tax during the banking crisis when interest rates were zero, my private pension collapsed, and the investment company I invested with went bust. Life has been a struggle ever since.

Does anyone know of a way to reclaim my capital gains?
