I don't mean any disrespect at all by saying this. Every journey of grief is different for each person.
But without our memories, WHO ARE WE?
I understand not wanting them to slap you in the face. There are streets I will not drive down because the memories of those places hurt so deeply, BUT, on the other hand, at times when I had no choice but to drive past those places, I have learned to tell the people there, alive or dead, who hurt me so badly (because the buildings did not hurt me - it was the people) to go ^&%$ themselves and I extend a hearty center finger - usually below the dashboard so other drivers won't think I'm cursing them to Hades.
That's a different kind of grief from losing a child, but it's still grief. The welling up of emotions, the overwhelming feelings, are the same - whether it's sorrow and tears or much anger - it's all emotions and memories and gives you something to deal with for a few minutes.
Gosh, I think the longest I've ever had to pull the car over and cry was maybe 20 minutes. But I take the time to do that, to feel the feelings and not repress them, because it's not healthy to keep tears or anger bottled up. They need to come out in safe ways, which is why I pull over. To shove them down can cause all kinds of problems with Denial, Repression, not being mentally present, etc. Even addictions, IMO, can start because people are repressing memories and not dealing with them. That is what I have learned over the years.
I'm not saying move or not move. I am not you, I don't have a husband to weigh in on the choice, and I have not lost a child.
I'm just saying, the memories are YOU. We are all our memories, aren't we?
