A few diagnostic procedures are needed to check if you really have hypoglycemia or those “attacks” are something else. According to your story, you had only one attack (on May 9, 2008) that was documented with a low blood glucose level. There are no data about the glucose levels during the further “attacks”. Without documented evidence for a low blood glucose level we can’t say whether or not you had a hypoglycemic attack. Those “attacks” could mean anything including real panic attacks. You may want to consult an endocrinologist about the possibility of having hypoglycemia.
