Cheers for the responses guys

Bud, glad you can look at things with such humour. Honestly, that was the way I dealt with things when I was younger, its been a bit harder the older I got I found. More responsibilities and stress. I have it a lot better than some, so if you can view it that way than I should be able to aswell.

Mark, I completely agree. That is the best way to answer it. The problem seems to stem from people who feel they've also hit their head and are 'fine'. I find this kind of links in with blame shifting, that you're causing the issue because they got a headache for 2 days and got better, not suffered for months.

Muss, I agree. I think most people struggle to deal with long term illness. Illness to them is something you suffer from for a few weeks and then 'get on with it'. Not something that drags you down for longer and longer durations. I can kind of understand the lack of understanding, until they try and offer advice, which nearly always equates to 'get over it'.
