Hey Smurf, You live in Boulder, aka "snobville" when it comes to all things cycling. Trust me there--20 years dwelling, racing, owning a small bike shop there made that very evident. It is great for cycling, no doubt, but remember where you are living--possibly the most elitist cycling community in this country.

A bike is a bike is a bike. It should be something that gives you joy, not something that reflects your self worth. I say hang out with the horse as much as you can; wherever unconditional love finds you, put your energy there. Enjoy your bike and ride it whenever and wherever you feel like it, and try to ignore those deluded folks who seem to think they (or you) are somehow better if they have a more expensive (or lighter, or fill-in-the-blank) bicycle. My dos centavos.

As far as depression goes you are getting great advice. I am no pro there. I seem to see my bouts of depression as personal challenges to plow through, and have likely suffered more than necessary as a result. But we all face it, especially when times are uncertain. You are not alone.
