In terms of redeployment options, I'm really not sure what there is. I have a big form to fill out with my skills, what jobs/tasks I'd consider etc, as well as hours and location. So I'll just put all the things I think would be viable and see what comes up. I am taking a 'hope for the best expect the worst' approach - in reality it is very unlikely that there'll be something suitable, not least because of all the budget cuts. But it's absolutely worth a try.
I'm not entirely sure it's sunk in. One colleague (who is having a baby very soon! Shows how long I've been away, I didn't even know she was pregnant) asked when I'm coming back, and I just blurted out "I'm not" oops. 
I'm kind of calm about that stuff, I only ended up crying when my friend was talking to me afterwards and I told her how I'm feeling really hurt by those colleagues who have completely blanked me. That's what's getting to me, despite the fact I know they don't matter, I have lots of dear friends (including some at work) who have been incredibly supportive, it's just that I really hate feeling so judged for having an illness that is invisible and subject to so much stigma and even downright disbelief. I sobbed a lot and was frankly a total wreck for a long time after, but my friend was so lovely.
