Is there anyone who is having to deal with a parent seperation in their twenties?

I'm twenty-seven years old. I wasn't under any illusion that my parent's were perfect... but I thought that they loved each other to make it work. I have plenty of friends who have had to deal with their parents getting a divorce, but always at a much younger age. The last few months my parents have decided that they no longer want to be together. When I talk about it with my friends who have parents who are not together, they are already so accustomed to it, that it is just the way life is. I feel like I am taking it harder than I should. I am adult enough to understand that things don't always work themselves out. But at the same time, this is hitting me way harder than I thought anything could. I have so many traditions in my family... and I am so pained to think that this year the holidays are going to be so different than they have been for my entire life. I just wanted to see if there was anyone else who can relate to having their parent's separate at such a late age. Any advice as to how to handle this would be amazing. Thanks!
