Hi Liz
You may not realise it but you sound like you have made heaps of progress, you made it through a week of work, you have a direction to move in with your treatment, you are getting help, you have some support. So give yourself a pat on the back, its not perfect but you are obviously pretty tough. A friend of mine going through this too said that we only let ourselves go to deal with the parts we can, when we can - it makes the whole thing take longer but we break it down - its hard if you always look at the big picture. Just getting out of bed somedays is worthy of congratulations!
Hope work is a bit easier this week - I haven't even got to that hurdle yet.
Cheers
Fiona
