larena,
Hello and welcome to healingWell. May I ask if "passing out" meant
you fainted or just fell asleep ?
Unless you and your healthcare provider are familiar with a
condition that causes you to faint, such as with situational fainting, fainting
is cause for a Dr. visit or, at the very least, a phone consultation with your
Dr. . Fainting can signal a serious underlying condition and should be
evaluated by a doctor.
Could this be a panic attack, perhaps, however I am not a
physician and cannot say for sure.
Do keep talking with us and know we care.
