A year-long vow of silence sounds like it would do you good. That's some major word burn out. Some people are natural born writers though, whether we are fancy successful people about it or not - we just like words and have an urge to formulate them. So I have the faith this is not a permanent burn out. It sounds like you are a person that belongs in the country. Pretty sure I would be seeking a vow of silence if I lived in the city too.

Having a nice quiet life fading into the distance while bothering no one sounds like a pretty nice and successful life.
