Hi coping ok
sounds similar to what I sometimes get I call it a mind worm lol
I have even been known to try and turn the raidio of when it gets to annoying , I then realise it's in my head and recite hickory dickory dock in my head and that will normally stop it for a while , though sometimes I end up with that going round in my head instead lol that's a pain !
Im 58 ish dx pd 18 months dx Lewy body 6 months but still find life hilarious ,use to be an hgv mechanic but alas no more as nobody seems to want someone with shaky hands and a poor memory fixing the brakes and steering on a 44 ton truck!
Anyway live well and always smile " it makes people wonder what you've been up to "
