Ah divorce.. I remember that, my Dad left 3 days after my 10th Birthday and I was the elder sibling. Everyone cried..
It is upsetting.. but it's not as if you won't see your Father or Mother : )
They're just doing what they feel will make themselves happier, although no offense.. I honestly think they should have thought about you and your sibling(s) more.
But yeah, try to think of it from their view, they just want to be happier and most likely will end up happier. After a while the idea of them not being apart will always be sad but it shouldn't feel so bad as to reduce you to tears, the first part is just coming to terms with it and accepting it. : )
But don't worry, you're not alone. It unfortunately happens to a great majority of us..
The divorce between my parents remind me to stay together even if unhappy for my children. I haven't seen my Dad for about 6 years now, but your Dad will see you
It might sound silly, but cheer up : )
Sorry for babbling by the way, I'm horrible at cheering people up or helping them for that matter, so if you want me to delete this post I gladly will ^^'
