I'm a bit of a serial poster, its an addiction
Ummm, I take it all back now. Having just read your other post, I'm not surprised this is such a large thing to face let alone handle and I don't think any of these jobs would necessarily be a good idea for you right now. I feel there are other things you would better benefit in achieving first and I feel these things are important.
I think your best step is in appealing the job centres decision and also assessing whether you can be placed on other benefits that take you out of the work-group for the meanwhile... or at least take in to consideration your full circumstances and operate around those to be sensitive of your needs.
There are groups you can speak with in order to receive advice and support from them in setting up the things you need to set up but I think in all honesty, this is your best option for now.. and screw anyone who tries to pressure you in to something you are not ready for. They won't be there to pick up the pieces if it all goes wrong.
Christ jess, I'm flabbergasted.
