I think that part of the problem with your workmates is that unless one has experienced a problem one cannot comprehend how hard the said problem can be. Mostly this is just ignorance not malice.
I know i have been unwittingly guilty of this myself. For example, many years ago i was trying to arrange a hotel for a group of friends and thought i had found the 'perfect hotel'. One friend, quite rightly, got really cross with me and said "you do know i can't walk that far from the train station"? Well i had forgotten as she could walk, but, crucially, i had forgotten not far. She was a bigger person than me and forgave me as i realized immediately what she meant and i was very sorry. So why am i saying all this? I suspect that your colleagues are busy with their own lives, they see you back at work and are not able to see how hard returning to work is for you. Your recovery is what it is, as i mentioned in a previous post, I believe way too much expectations on what we should be achieving. Because my husband can see me pottering about he is already slacking off on his attention to me. On one level i don't want a slave but on another...
We all need validation for our struggles, that is not the same as pandering to victim hood, but an honest acknowledgement of ones experiences. I get the impression that your colleagues don't have the slightest clue how much that you have achieved and the almost superhuman effort it must take to get to work when not on top form. With all this you have maintained a fantastic sense of humour and write with wit and compassion. You also give so much hope to your fellow hipsters, i have been lucky enough to have such support from you.
Apparently a really good thing to improve ones immunity are breathing exercises. This means that fresh oxygen is perfusing ones tissues. There are loads of different methods if you Google it. The main thing to remember is that the out breath should be longer than the inhale. So, for example, breathe in thru the nose for 3 and out thru the mouth for 4. I set a timer on my phone to go off every hour and i try and do some then, my reason was to try and calm my sympathetic system down, but, i read it can affect (positively) ones immune system too.
Hope your weekend is good, i love Saturdays as i go mad and get loads of papers, perfect excuse to do nothing.
