There are lots of things you can do to make yourself feel better.
The most important one is to keep doing the things you like to do. Try to keep up with your regular activities. See your friends—don't isolate yourself. Read books. Listen to music. Play with your dog or cat. Take long walks. It's not just OK to have some fun during hard times, it's essential!
Make sure that you take time for yourself everyday! When life gets stressful, it's easy to forget to do things for yourself, even though times of stress are when you most need time for yourself.
Here are some other suggestions:
Talk about it:
One of the best things you can do for yourself is to talk. Talking about your feelings—not just once, but often—almost always makes you feel better. It releases tension, and can help you put things into perspective, so they don't feel so overwhelming.
So:
Write about it. Try writing about your feelings in a journal or diary. You can write as often as you want, and say whatever you want to say. Over time, you will be able to see the progress you are making as you adjust to the changes and face the challenges.
It's OK to cry. Crying can make you feel better, because it lets the feelings out, instead of keeping them bottled up inside. But don't worry: if you don't feel like crying, that's OK too.
Exercise
Get active! Exercise is an excellent way to let off steam. And being fit physically may help you feel good emotionally.
Do something creative
Think positive
Things will get better! Parental separation and divorce certainly are hard at first, but you will get through it. Others survive, and you will too. You might even find that there are ways in which your life is better than it was before.
