Welcome to Psych Central (PC) Tammy. Sorry to hear your daughter has been suffering from nighmares. Some people at PC will find a therapist that specializes in children to help them sort out what may be troubling your child.
Getting sleep may be the single one thing that keeps me in balance. If you or your chlid are not sleeping or having bad side affects, contact your doctor or psychiatrist and tell him what is happening so you can make adjustments.
Many people find compassionate, caring people here at PC. Some people find the forums give them the compassion and empathy they seek.
