Hi MamaG...
I have unfortunately lost both my parents, my dad 5 years ago and my mum 1.5 years ago.
My dads ashes are scattered around a tree near where I live (and where I grew up)
My mum is buried in the church just by the woods..
We didn't scatter my dads ashed until the day of my mums funeral (as just never seemed the right time etc).. and I have to admit that I do go there often.
Mostly because the tree right next to the path, but everything I go past I touch the tree and say hi to my dad (DD says hi to grandpa, even though she never met him).. realised the other day that she actually thought he was in the tree!....
I have to admit to not visiting my mums grave all that often anymore, I did when she first passed away, and did get a lot of comfort from it (and I did sob and sob)
but actually find it harder now and don't really get much from visiting the grave... but it's nice to know that it is there should I wish to go.
I would fully recommend that you go and go until you no longer sob and sob as it definately does get easier and it think you will find some benefit - but maybe not the first time you visit, it may take a few times..
I am moving away from here soon and I have no idea how I will feel being so far away from why they lie (although I know that they are in heaven etc)....
Go for it MamaG but as I said you may have to go a couple of times to really feel the benefit... hugs being sent your way (and I don't often do hugs)...
