Thanks Fuzzybear, WeepingWillow and Carmina for the encouragement and support.

I agree with WeepingWillow, I perhaps didn't 'sell' my need very well and pursue my GP to try and sell on my behalf.

My wife tells me I tend to underplay my difficulties when describing it to the GP, but at the same time, I think my situation is bad enough that I don't think I need to have too 'sell' it any further.

On the tax subject, I pay 40% tax. It's a pretty broad spectrum and there is a general guideline here -> https://www.gov.uk/income-tax-rates.

I think the right thing to do is to meet my GP and explain the situation again, but I don't look forward to this. It is stressful and I don't like to ask a second time when something has been denied already. I don't like confrontation or having to explain what I am going through (differently) again.

I think it is so much easier explaining physical pain vs mental pain.

@Willow
Out of curiosity, what do you do now? It's ok if you don't want to say, I would understand.
