Awesome. I love bookstores, too.
The No-Bullshit Guide to Depression should be available at basically any bookstore in the world (though I can't tell you if it will be in stock when you go!).
But, to help find a location near you, here are a few retailers who I've confirmed are carrying the book, in some of the countries where my writing is most popular.
Don't see your country listed?
No worries - I simply couldn't list everywhere. Give your local bookstore a call, and they should be able to order it. And if all else fails, you can order direct from me!
