Thanks so much for your responses @kezmusc @kitkatb @Afraser @"~Millie~" @arpie @Sister @Blossom1961
I really appreciate you taking the time to reassure me that being all over the place emotionally is a normal part of the process.
On top of returning to work, I've also just started a course which runs for three hours two nights a week for 16 weeks - and then 20 weeks in the second half of the year. I'd signed up for it before the diagnosis and didn't want to put it off for another year. I might just have to muddle through this semester and give it my full attention next semester.
@kezmusc - I hear you about wanting to get back to the 'normality' of work. I think a bit of normality would be good right about now. I might be expecting a bit much trying for normality when I haven't even started treatment, so perhaps I should cut myself some slack.
My manager is great but I'm beginning to feel the pressure from other colleagues (who only know I've been unwell rather than what's been happening) and I'm not sure whether to tell them.
Anyway, I'll work it out. Thanks again. It's great to be able to read others' experiences and to know that dealing with this is personal but that there are parts of it that are common experiences.
I'm in Melbourne and have a lovely (all female) team. I've read some posts where it seems not everyone has compassionate, caring professionals on their team and that must make the whole thing much harder, so I'm very grateful that at least I have that.
