Employment Tribunal Help

Hello everyone.

I have to take my previous employer to tribunal as they constructively dismissed me. I made an error in July last year and it really caused a long term meltdown which kicked it all off. 

I am lucky as I was known as the 'Autistic Lawyer' in New Zealand where I was a Barrister. However, I am looking for an expert witness who can analyse the meltdown and assess whether it was AS caused and what symptoms were shown.

Anyone have any ideas please?
