DS (22) has just returned from a year travelling after doing his degree.
I was so excited to see him and have him home for a bit, but he is basically miserable to be here and has spent the entire time telling us how he is emigrating back to the other side of the world the minute he can. Home town is boring and why would anybody in their right mind choose to live here? His previous plans to follow a career in his very good degree are now abandoned and apparently he can't tell me stuff about his life any more because I'm too old fashioned to understand. He's already announced he'll be away again for Christmas this year and has shown almost no interest in his younger sibling who is also doing exciting new things. They used to be really close. He hasn't once said he's pleased to see any of us only the dog 
I know it's normal. I know he has to grow up and move on but how do I stop feeling unneeded, weepy and hurt? (Not showing it to ds). 20 years getting him happy and independent and now he is happy and independent - and I'm turning into a nightmare clingy mother wailing but what about meeee?
Please talk sense into me.
