Autistic and me

I had a bad cold recently. Yesterday I felt like I’m getting better but today I feel worse again. I was going to find my water bill today to finally pay it, which would still be 6 days after the deadline, but with this cold it may not be possible. I wonder where it is though, I normally dump letters in the kitchen, by the microwave, but this time the bill doesn’t appear to be there. If I still can’t find it in the next 3-4 days, I may need to call Thames Water and admit my lack of organisation skills.

I wonder, should I just say I lost the bill or should I explain that I lost it because I’m autistic? But doesn’t the second option sound like if I am trying to find ways to get out of paying it? It’s really difficult sometimes to know how neurotypicals may understand certain elements of communication.
