I feel your pain. I am in the same boat. I am trying to give my son space too, but I miss him! Letting go is hard. I know that it's a good thing that they want to be independent and figure stuff out. It means we did our job.
Back to you! If I were a drinker I would have said let's get together for a glass of wine, even virtually. But my MO when I'm down is ice cream or cookies, and that's not a good thing.
Back to you!
