How bad is anxiety supposed to get?

I heard it can get pretty bad. I started crying when my teacher asked me a Вопрос in front of the class... еще and еще anxiety leads to panic attacks.

Do Ты mean - what is the worst that could happen when you're having an anxiety attack?

It may sound silly, but the worst thing that could happen - is that Ты forget to breathe! Which could result in fainting. Ты can NOT die from anxiety (comforting to know).

If Ты find your сердце beating like that again, try focusing on your breathing, try to breathe еще slowly and deeply.

Always a good idea to speak with your doctor about such things.
