I am the father of a 19 y/o daughter with a lot of anxiety issues. Highly intelligent university student & has always made straight "A"s taking the hard courses. Never had a boyfriend or girlfriend despite being a slender and attractive girl, though she does interact with people at school and organized volunteer events. Outside of school, she never leaves the house. Stays up all night studying, surfing the internet, & playing an RPG videogame. The only time she is awake during the daytime or evening is if she has a class. This sleep schedule has been going on for a couple or three years now. Takes Zoloft prescribed by family doctor and has some Xanax for situational use but does not take it regularly. Does not drink or use any illegal drugs. Lately is very confrontational with Mom & Dad. Says she is happy, understands she has an anxiety disorder, and does not want to see a psychiatrist or therapist or go through any therapy. Her lifestyle is driving Mom & Dad a little nuts & we would like her to have more from her life. Thoughts?
