Has your memory been affected post treatment?

Whether it's the chemo, the lack or hormones, trauma from the diagnosis and or the surgery, lack of sleep or all of the above, I'm afraid what's left of my brain is truly stuffed. I've always been very fluid in my speech and vocabulary and have used words as tools, playthings and even weapons in the past. Now I'm reduced to everything being the "thingy" The clicky thingy (remote), the sucky outy thingy (usb stick..it sucks out stuff from one computer and spits it out into another), the picky outy thingy (tweezers), the cutty thingy (scissors) and so on. Maddening!!! Numbers are just hopeless...I get them all muddled up and back to front, or just forgotten all together. Me being reduced to tears in the bank when I was trying to withdraw cash from the atm and my pin number was a mystery to me was terrible. When doing the shopping list, if I get distracted, I have to go back to the beginning...washing liquid, fabric softner, bleach, Preen....etc. If I'm up to, say, Whiskers and kitty biscuits and the phone rings, I have to go back to the washing liquid and start again. It seems for me that it's the sequences that get scrambled. For me being titless and hairless is one thing, but by far the worst is being witless...sighhh...
