At what point is it considered anxiety?

You stepped into an unwanted situation or a haunting memory crept into your mind. You feel your mind racing, your heart almost stopping every single second. You feel the bile in your throat like a candy you swallowed forcing its way up. Your mind gets blank that you don't remember what happened or why you're feeling anxious. You can't think what's the next step. It all settles down when you step out of the situation or snap out of your trance to assure yourself. The blur starts to clear and you can see again. You're good. Just the usual occurrence.

When you're constantly thinking about things, worrying and obsessing over them. You might be irrationally fearful of certain situations, people, or thoughts a lot. Anxiety is intense, it can paralyze you with fear. Fear, stress, and anxiety are all related, but very different.

Some people who have anxiety find themselves worrying constantly, feeling like something horrible is going to happen all of the time. A sense of impeding doom. Others fixate on things and situations. They have panic attacks.. Etc. Anxiety is more than fear.
