Anxious about anxiety

Sofia

Hey/so I’m 16 and recently went to the ER for what I thought was a heart attack, only to learn that it was an anxiety attack. The attacks have happened to me a couple times since and it’s kind of hitting me in the form of tiredness/lack of energy in my daily life, as well as mood swings. Advice would be so appreciated about what the heck this is/ can the birth control pill effect/cause it?
