Plant killing zombies to take my mind off things

Would you believe I've played this game continuously and countless times for 6 years? I don't know how many rounds I've completed. Twenty or thirty maybe? And each time I finished a round, I'd happily start all over again using various strategies I have not tried before.

It's not entirely a brainless game but I've played it so many times, it's so easy but it takes my mind off things, which is what I needed today.
