First of all, i appreciate your knowledge of a diagnosis as "Social Phobia". Social Phobia is an anxiety
disorder. I guess Social Phobia is very much a common disorder where in the people suffering from it have a typical thinking that they might behave in an embarrassing way or they would be afraid that they are being scrutinized in any social situation. It depends upon whether it is related to any one specific situation or generalized across many situations. Also one should assess for whether there is any other condition along with it. Depending upon it the treatment may be planned. And it is very much a treatable condition. The treatment involves a combination of medications and therapy/ counseling which can be done by a trained mental health professional. I suggest you to consult a professionally qualified Psychiatrist
for the initial assessment and the medicines and later the psychiatrist can do the therapy or your daughter can be referred to any clinical psychologist
for the therapy part. I hope this answers about your daughter's issue. i would be glad to answer if there are any more queries.
Thank you and wish your daughter a good health.
