The best thing would be to call a vet for proper diagnosis and treatment. Horses are normally cheerful and energetic animals, so the lethargy you are observing indicates a big problem. Make sure you call the vet immediately because most diseases get worse with time.

Call a vet immediately! Your horse could be colicking or foundering. Its important to call a vet right now!
I've owned horses for well over a decade, and from the short description it sounds like colic. Colic is very deadly and requires vet attention ASAP. Other symptoms are bloated belly, kicking or biting at the stomach, sensitivity to being touched there, and small or no bowel movements. No poo is a DEFINITE indicator of colic, but so is laying down.
Call your vet first and get their advice. While you wait for your vet you need to get mineral oil - most barns have it stocked up for this reason - and a big syringe and start feeding your horse mineral oil. LOTS of it. You need to get your horse up and walking as much as possible to get the food and gasses moving in their system.
Get your vet out to your barn NOW.
Indicators of founder would be limping, hoof and coronary band that are hot to the touch, and swelling hocks. This ALSO requires immediate vet attention. I had to put a horse down because she foundered - the bone in her front foot began to literally sink through her hoof, and would've gone through the bottom eventually.
horses or very noble animals they do th best that they can to hold in there pain but you need to get a vet there but it doesnt mean the horse hurt it could be depressed and that needs tender loving care but you still will need to get a vet just in case it is something else.
