I, also, have had trouble with confusion and counting.
I have reached an all time low, trying to fill in an answer on a form for my solicitor. All I needed to do was add three numbers together. I used the calculator on my 'phone, thinking I'd soon have everything done and back in the post.
Not as simple as I'd hoped. Even the calculator came up with a different answer three times in a row.
There is no hope for me
