Is every free moment in your life spent reading?
Just about.
Is your TBR pile bigger than your expected lifespan is long?
Between my pbooks & e-books ...yeah.
Would you rather be reading right now?
Yeah...In a way I am. I'm reading this board instead of working. 
If you said yes, here's a question for you:
Before you became an Obsessive/Compulsive Reader, did you have other obsessions? Hobbies? Collections?
I can't remember when I wasn't an O/C reader, but was limited by how many books the library would let me check out.. But I also have 6 dogs(and if I had room....
) & I used to collect teddy bears...Finally had to donate them in order to make room for all my books.
Do you still?
Collect things. Not so much anymore. There is only so much room. Between my pack rat husband & my books & the small house we live in... 
Has reading satisfied your need?
For the most part. I still get urges to adopt more dogs,
