@EachandEveryone I can understand you feeling apprehensive. When you say 'people' do you mean colleagues? Do they not know why you've been off? (Sorry, I don't know what your job is.)
I've been off for two months now and I can't imagine going back for a while yet. I'm physically not capable, but I'm definitely not mentally strong enough. I manage a small team of strong personalities. I like them a lot, even the tricky buggers, but I need to be mentally strong to cope with them. One of them starts every email "I hope you are well...". I had a word with him about that when going through chemo last time and he does seem to have stopped. Another is nearing retirement and bangs on every day about how old he feels and wonders how many years of retirement he'll have. His parents died in their 60s so I can understand his position, but as I'm very unlikely to see retirement it's very insensitive for him to say these things in my presence and I have to swallow the temptation to say something cutting.
When I returned with chemo hair no-one mentioned it, other than those who knew what I'd been off work for. I think most people understand that it's not something they should bring up unless you do. Hopefully tomorrow will be a positive experience, but we're here for you if it's not and you need to offload xx
