I agree, many things can start you off crying, as Julie stated music is certainly one of them, certain songs make you weepy, photo's of course. I have a photo of my wife protruding out from the flap on the passenger side sun visor, it was just a bit too much having it on the drivers side (had to think of the safety of other road users)
In reality, it's when you think about them, what you had together, and now it's gone, I don't feel sorry for myself so much, I feel upset because she shouldn't have gone yet, it was not her time, it's me that's had 4 heart attacks, so I always thought as did my family that I would go first, but things don't always work out the way one expects.
Though I'm not doing it myself yet, I do think the long term solution to help ease the pain is to seek out more social interests, meet new friends, easier to say than do I know, anything to fill part of that huge hole left in our lives. Whether that will happen in time I don't know, but sharing our feelings on here is a start, as others just don't understand, indeed my 2 sons grieving ended at their mothers funeral, totally opposite of how I feel.
A Day at a time people.....a day at a time.
Take care... Brian....
