It is a beautiful sunny day and you head out to feed your horse. You notice a gate is open, or a fence is cut and your horse is missing. At first, you think you are not seeing things correctly, and you call to your horse. You are sure he must be behind a tree where you can’t see him. Your heart rate elevates, your respiration rate increases, you start sweating no matter the outside temperature, and you get that terrible burning sensation in the back of your throat.
