Background is I'm in recovery from an eating disorder and struggling with the weight gain. I've been working from home a lot so I'm not physically in the office much.
An older male colleague who is slightly eccentric and has a funny sense of humour, but who I like on the whole and who sits next to me, said "You're usually... ....You're not - you know - are you?"
I was so busy trying to find a crack in the ground that I didn't feel like explaining that I'm in recovery and the body tends to want to cushion your internal organs first, and that plus the side orders of water retention and wind means my belly is very distended.
Now I feel awkward and embarrassed - I had even expressed to my line manager that I was worried people might comment on my weight gain and of course he told me I was being ridiculous...
