You can't get upset. The body does stuff and it isn't your fault. The wind isn't your fault. I used to have sciatica due to two ruptured disks in the lower back, and what you did is phenomenal, cycling with that level of pain, and then battling the wind. Part of cycling is being smart and knowing when to quit or turn back, so that your body can heal and get better so that you can bike another day. I've completed some rides when I should not have done so, when the smart thing would have been to have done the metric or the short-ride, or just not have shown up for the ride; I look back and realize how dumb I was. You will look back on this ride and know how smart you were to have stopped, that you made the right decision.
