Feeling tired & drained

Hi there,
I was talking to my sister on phone today. She was telling me something about electric cables being relocated on our land (C). I found it hard to follow and boring (T). Felt very tired, drained (F). Didn’t speak back to her much (A). Ended up dissatisfied and worried that there is something wrong with me as I have very low energy and easily get tired (R).
How can I find a different thought about a boring topic? Should I think something positive about electric cables?

Thanks a lot!
