It's an interesting discussion here. It caught my attention because I really want to take my young teen lad to see Inside Out 2 and I have also just had a quite overwhelming 8 hours of anxiety which is just passing now - the ringing in my ears is just ebbing away and I can breathe deeply again without it feeling forced. It started building yesterday in anticipation of an event but almost became unbearable immediately prior to the event and lasted right up until 20 minutes ago.
I don't usually suffer like this. It was brought on by an emotional event I arranged. It went ok but I have been very taken aback by how much it affected me physically. For the last 2 hours I have relaxed and told myself the golden words 'this too shall pass'. It did luckily.
If I was experiencing that intensity of feeling and I didn't know it was going to go away I think I would have been terrified. However, I knew what had caused it, I knew the situation was coming to an end, I told everyone at the event how I was feeling and they understood and we rallied on.
I get a very, small amount of nerves/worry/anticipation before many things, often nothing at all phases me - but anxiety is different, it grabs you by the chest and won't let go. You can't purely 'pep talk' yourself out of it like you can with feeling a little anxious.
Alarm bells would be when anxiety does not shift once the stressful event has happened. In fact. if no stressful events are happening and you can still get severe, non-ending anxiety. This is when it's see a doctor time.
I think it's important that teens recognise this difference and know when it's overwhelming but manageable as it's due to a known cause and so shall pass, or if it's non-ending, not caused by anything in particular - this type needs someone to help you - it won't always go on it's own.
Sorry I wrote an essay! I hope it made sense
Just glad my ears have stopped ringing and can breathe again
