when it takes a step south, the feelings felt are a good test about the overall level of how things are.
the hole in the stomach is a good thing then, cuz even tho it doesn feel very fun, it is an indicator of care.
through the nervous worry shines the cause for the worry, the cause that makes it all worth it again,
therefore the gut wrenching feeling is good;
whereas the lack of it indicates an apathy that should be cause for a different kind of worry that is not good.
