Glad to hear that you are not going for the surgery. Don't be scared regarding what the doctor is telling you. Increase the steroid dosage for now, but continue juicing many times/day to be able to wean off the steroids.
There is no doubt that psychological health impacts physical health-the mind body connection. Going back to Bulgaria may improve your health, but continuing following the natural protocol (juicing, slippery elm, probiotics...) is just as important.
I did lose weight when I had flare ups. But I also gained tons of weight while on steroids. I'm surprised that you are losing weight, instead of gaining weight, since you are taking the steroids.
Be positive, and don't be scared. View your colitis as a learning experience....
