Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. You have lot of information available at internet about schizophrenia. This wikipedia page should give you enough information - http://en.wikipedia.org/wiki/Schizophrenia. Go through the site and judge yourself if it is for your friend. If you want to diagnose yourself (some people mimic their symptoms with others), please do not do it. Leave it to a psychologist or psychiatrist. In any case, as your friend has other symptoms which corresponds to bi-polar disorder and addiction, you should take her to a psychiatrist as soon as possible. Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe some psychotherapy techniques which should help you cure your condition. Hope this answers your query. Available for further clarifications. Good luck.
