Kidshealth.org suggests that you:
* see a therapist or counsellor if you need to;
* talk to your parents about your concerns;
* try to keep your normal routine the same, for example, sporting commitments, music lessons, hanging out with friends etc (this can be difficult when you're living between two houses);
* take care of yourself - get plenty of sleep, exercise and eat right.
