Why not write about your “boringness”, self-deprecatiion, when presented well, can be very funny and best yet, unique. You just don’t want to sound too self-doubting. Write about your constant worries, and your “coping” strategies, you might be surprised at how good you are at presenting a fascinating self that is worth knowing.
I am kind of a homebody myself so I found your life not to be boring at all, but pretty self-fulfilling.
