My parents are getting divorced. What do I do?

I'm only 12 and my dad wants a divorce. It's probably going to happen. I am so upset right now and I can't get a hold of any of my friends since it's a Sunday night...... My parents wanted to get divorced when I was way younger but even though they sorted it out, I went through a whirl-wind of depression for years and finally got out of it. I'm starting to get depressed again and I have no idea what to do. My whole life has revolved around constant fighting.. It upsets me to hear them fighting a lot. I've always wished to just have a normal family that loved each other like my friends, but instead my life is a hellhole! Help :'(
