I got a used 2016 Kawasaki Vulcan from craigslist in March of last year, instead of therapy. One of the best decisions I've made.

Both is good. When your bike breaks down and can't be fixed for a month because a mechanic that can rebuild the engine isn't available or the repair is too costly, that can be a real hit to your mental state (trust me, I know). That stuff doesn't usually happen to a therapist. But also a therapist won't make you happy, just less unhappy. A bike will put a smile on your face.
