Chemo brain -overwhelmed by my life

My brain turned to oatmeal porridge during and after chemo...also still on letrozole, which I don't think helps.In the beginning it was words...what the hell were they, and where were they hiding? Everything became the thingy...the clicky thingy (remote control) the cutty thingy (scissors) the picky uppy thingy (salad tongs) and so on. Numbers were a nightmare...all the wrong way around and forgot my PIN number in the bank which resulted in me bursting into tears. It has improved, but I still have great difficulty remembering things. I'm a total Luddite and use old school methods. I found that having a visual reminder of upcoming tests and appointments for the month to be useful. No help to only know the day before for many things, so my husband printed up a monthly calendar sheet for the year. As I get an appointment, it gets filled in on the day block for that month. For some, I have a request form for say, bloods or urine to be done a week before the appointment. This is filled into the appropriate date block...as well as if it is a fasting blood test, or first urine of the day. My husband has learned to call out phone numbers two at a time, or else I flip the numbers around as in 948 becomes 984 and so on. My appointments are many as I have a number of health issues and see a rheumatologist, cardiologist, pulmonologist (lungs), nephrologist (kidneys) haematologist (blood), oncologist, neurosurgeon, breast surgeon, G.P. ....and a partridge in a pear tree.... so as you can imagine...keeping ahead of it all is difficult. Is there any way you can get your teenagers to help more? When my kids were that age, they had set jobs that were theirs. No job...no pocket money. From the age when they started school, they had jobs. Little jobs like feeding the cat, bringing in the post and the like. They soon learned to carry their weight and that was loooong before the cancer shitfest. I hope you find techniques that work for you and your family.
