I'm impatient with everyone- especially my husband?

When I feel like someone is beating around the bush with me or wasting my time, I get really frustrated and lash out. The way I figure it is- both my mother and my grandmother died when they were in their forties, so if I go by that I'm already past middle age (I'm almost 31). So I don't really have time to fart around and wait for indecisive and wishy-washy people- I figure I don't have that much time left as it is so every second is important.
