In reply to Yvonne M ..
Typically I am just starting on my 'downward part of my cycle' .. (funnily enough I can always tell when I am about to go 'down' as my spelling gets to be atroshus nd I mack lost of tpyos) heheh .. just in time to be 'at my worst' over Christmas .. but that's no matter as I am not going anywhere and I've done all the shopping I need to ..
.. I've long learnt how to cope with the bad weeks .. by stocking up in the good weeks ..
The 'heel pumping' I did on my scooter was surprisingly quite succesful .. so I think I know where I am starting on my fitness levels .. rock bottom .. no untoward 'extra' pain .. although I was a bit tender in the back of my calves and achilles heel .. although a few clicks of my 'pain pen' did wonders to ease that ..
Re: Physio .. no longer available on the NHS for 'long term sickies' in my area . unless you have a 'new' problem .. and on my miserly incapacity benefits I can't afford to go private .. one of the 'catch 22' problems I have is that I am still officially 'off sick' .. from 1993 ... I won't work again .. but leaving me on the 'off sick' register means the Government doesn't have to count me in their statistics .. because once you've been off sick for a specified time you 'drop off the list' .. if I could be classed as 'not fit for work' I would actually be better off financially and helpwise .. New Labour - "we care for everyone" ... NOT ... 
Re Diet: Hospital nutritionist gave up with me .. to eat enough to be healthy I put on weight .. to eat to lose weight I get ill .. all down to my totally sedentary lifestyle
.. but that is all going to change .. I simply can't afford to sit around any longer and be told 'you are too unfit to exercise, but if you don't lose weight you'll die young' .. doing as I have been told to do for 10 years has only made things worse .. I have nothing at all to lose and years of life to gain 
I know it won't or can't change in a few weeks .. this is a long term goal .. but hey .. I have started out on the road .. "do or die" heheehhh ...
I think Runners World forum folk are just what I needed to 'get me going' .. thank you to everyone who has taken the time to read and more importantly post a reply to my plight .. you really are wonderful ..
and I really do appreciate all the help given ..
