Is it normal to want to die because of my parents divorce?

It's not normal to feel like you want to die. Talk to an adult you trust (such as a school counselor) immediately. If you get suicidal urges then try calling a suicide hotline. If you are able to, try talking to your parents about seeing a psychiatrist.

I can understand that you're feeling bad but you shouldn't let their relationship affect you emotionally. You don't need to pick a side and you don't have to leave them both if you don't want to.
Because they're doing what's right for them you should do what's right for you. If you feeling suicidal please see a therapist or even just a friend who will listen to you.

Just wait till they start "moving on". When they throw you away for their new family.

I'd take you. Except the Ratman has two adult children of my own. And they constantly bust my chops. With good reason. So I guess the Ratman taking you in would be a bad idea. So focus on your own life now. You'll be old enough to find a partner in life soon. And this will be wonderful! You just wait and see!
