It is pretty normal to get a little carried away with a remodeling-project. But when it turns into overspending that is a sign of hypomania I think. I recognize myself in what you are describing. Try to take a couple of days off from anything that has anything to do with the remodeling project. Do something else that you enjoy. It is normal to be able to take some time away from a project like that, but if you find yourself unable to do that, or if it is extremely hard to do it, then I think I would assume it is hypomania (or at least beginning of hypomania ). I am speaking from my experience. Hope it will help you!
