I've heard other widows say it...the 2nd year is worse. I don't know if that's entirely true, but I sure have noticed that I'm missing more of the stuff I never thought I noticed before. Weird things...the dimple on his back, the tatoo on his arm, the way he smelled after a shower, the softness of his hair after a haircut. Then there's the hair in his nose and ears and the sound of snoring (all night).
So, the first year was the year of shock, anger and extreme pain. It's the year of trying to find your footing, of trying to grasp the enormity of what has just happened. In some cases, there is also financial issues to deal with. Mostly, we are completely crazy.
The second year, I think, is the year that you really have to come to grips with the fact that the physical person is gone. The shock has worn off, but you still kind of expect to see him walk through the door any minute now. It amazes me that 15 months later, the sound of a car door shutting outside my house can bring me to my knees. It's the year of understanding just how much life has changed.
