Post-treatment Tired and can't afford to be

Hi there,

I am a 60 year old who has had a pretty-easy, early-invasive BC journey: Small, ER+, PR+, HER-; Lumpectomy with clear margins; 2 lymph nodes taken but uninvolved; Axillar seroma drained; 15 fractions of RT; Maybe some early lymphodema in breast, Letrozole from diagnosis through RT but then told I would not benefit much from it (0.6% benefit in reduced recurrence rates) and discontinued it due to side effects.

I am 4 months post-surgery and 6 weeks post-RT, and have been off Letrazole for a month or more. I am back at clerical work (work from home) full-time now, after working back up gradually, and I am stuffed!

I can barely get out of bed in the morning, and if I can stay upright in my seat and keep my brain focussed, by the end of the day I am completely useless. Rad Onc says the fatigue should not be RT related at this point.

Now I feel like I should be able to just "snap out of it" but that's totally beyond me and I just want to cry and sleep.

(For transparency, I should maybe admit (& remember for my own benefit) that since my initial biopsy my husband and I have organised a son's engagement party, done a road trip and purchased a home 1500 km away, organised renovations and done 2 more trips to keep tabs on the works, watched 2nd son sworn in as a cop, and seen no. 1 son marry. Maybe that's part of the fatigue ...along with the panic over working full-time, decluttering/downsizing, packing and moving in 3 months.) Maybe my problem is actually a dose of insanity...? 🤪

Can anyone with a similar, "straightforward" BC journey share whether their "normal" returned and how long it took?

Thanks for "listening".
