Does anxiety ever entirely go away?

Probably not entirely, but that doesn't mean it will always control your life. Anxious types can always find something to worry about. And, if you are that type, you will no doubt, always lean in that direction.

It's difficult to completely rid yourself of anxiety. However, it can be diminished with proper techniques.

No it does not. Some students or even adults any age feel like talking would embarrassed them completely. Or acting or maybe a job interview

Honestly my anxiety is always there, sometimes its just niggling in the back of mind, little worries and sometimes it blows up one small worry or several small worries into something massive. And sometimes the massive worries worry me so much I have a panic attack. Anxiety is never fully gone for me I just learnt to distract myself when those small worries start whispering.

Anxiety for me is more of a fluid state than a solid object. If my mind is like a calm ocean, anxiety is like the waves that disturb it. It can't go away entirely, but I can learn to calm the waves and ride out the storms when they come.

I do not think Anxiety is a permanent thing, it comes and goes when we are feeling anxious about something. For example one day you might not have to do anything or do something but you are comfortable with it and not anxious and then the next day start to feel anxious about something. Everyone regularly in their lives gets anxious about something and that is completely normal, so I do not think it ever goes away but at the same time I do not think it is a permanent thing, more of a triggered reaction to something you have to do.

I don't think anxiety ever entirely goes away. I think you just figure out how to deal and cope with it.

In my experience anxiety never entirely detaches itself from a person! I think we learn to control it and tame it from a roaring lion to a timid kitten with constant neutering it will behave but its always there!

Ofcourse anxiety is a feeling and like all others it will pass away in matter of time,it is just a serious feeling which needs to be adressed rather then happiness or sadness it takes time to treat anxiety but it is treatable

Entirely? I'm not so sure about. But anxiety can get less powerful. It can go away partially, if not mostly.
