Parents getting divorce in their 50‘s

I totally support their decision as I have seen them fighting suffering all their life. But I am getting weird feeling, frustration, or whatever it is!! I dont know how to explain this feeling!! Even tho im in my mid 20‘s only child and i dont live with them, I know Im old but how do I help myself? I dont even have any siblings and I dont like discussing with my any cousins or relatives and I feel low. How do I get this feeling out of myself, throw it out , come clean??
