I was sad for a while when my parents got divorced, because the idea of them being together forever is drilled into your head for most of your younger years. We did set up a schedule throughout the week for swapping between houses, I'm really glad custody didn't go one way or the other, I'm still not sure why they got divorced. You get used to it as time goes on though, maybe quicker than you think.
Though it has been hard because, my dad has depression and anxiety issues. Just recently found out he was bipolar, then because of his depression he stayed in the house all day, and got blood clots. So he had to go the hospital and stayed the for a while. He just got out and he is doing a lot better. So the basically, everything mostly gets easier as time goes on.
