Divorce is difficult for everyone involved, but most especially the children. No matter the age, children tend to deal with two things when parents are splitting up: Blame and powerlessness.
Teens have the tendency to blame themselves, thinking that the divorce is their fault.
And, at the same time they feel powerless because there is nothing they can do to keep their parents together. There are some things teens can do to cope with this stressful situation, however.
First, see it for how it really is, but not worse than it is.
The parents are divorcing because of their problems, not anything the teenager contributed to. You may want to blame yourself, but it is not your fault. What you can do is be there for your parents.
Take on the role of the parent while your parents are the ones acting immature.
Let them both know you still love them, especially when their decisions are rocking your world. This has an added benefit as well. There is a chemical in our brain that produces feelings of well-being called Oxytocin. It only gets released when we help other people. So, by helping your parents through this difficult time, you also may lower your stress and lower the possibility of depression. And, if nothing else, you can hold your head high knowing you did everything you could.
