18 year old female, 4-5 hours sleep for past 9 months. how will this effect my health? very anxious too and pocs. can napping during day be worse?

4-5 hr sleep not: enough for most people. A brief nap during the day may rejuvenate you. Keep it brief,no more than 45 minutes....

See below: Inability to fall asleep easily is often due to anxiety. Inability to stay asleep(early awakening) is often due to depression. For information on treating insomnia see http://bit.ly/260HSXL and http://bit.ly/1ZOS1D8 For good advice about napping: http://wb.md/1UxS4PA For treatment of anxiety Cognitive Behavioral Therapy is very good.
