While I have not been down that road, I can certainly agree that cycling makes me feel better about life in general. I'm typing this as I am getting ready to go for another ride this morning - one that I have been looking forward to for two days as things came up that prevented my rides the last three days.
Wish you, and others in your position, the best and hope you continue to find outlets and reasons for enjoyment and happiness.
Best of luck to you.
