New custody order finally settled, feeling weird about it

After 18 months of back and forth, we finally got a 50/50 custody agreement signed. I should be happy right? But honestly I feel kind of empty. The fight was exhausting but at least there was a goal. Now I've got them Monday through Wednesday and every other weekend and it's good but I keep missing the days I don't have them. Anyone else experience this after the legal stuff is done?
