Hi Karen and nick!
ill answer cos this is a subject close to my heart too. I had similar, except with a mastectomy and felt really tired for AGES. I was applying for jobs at about the stage you are at now, and couldn’t cope with the interviews. Any stress or decisions at all would fill me with anxiety and set my crying. So you’re not alone. I kept posting on here to find out if it was normal to be so tired and to take so long to get better.
And yes, it seems that it does.Slowly.. I don’t know the answer, other than to say, you are working and running a house - which is tiring anyway. Good luck, I’d like to be more help, but ironically I’m too tired!
