Feeling anxiety is a complete waste of time. Unlike pain, which protects us from dangers happening now, anxiety does nothing to protect us from dangers that might someday be.
Are u suggesting people voluntarily get anxiety?
I'm suggesting you can voluntarily suppress it.
Maybe for some people, but there are different levels of anxiety. For me my panic attacks used to be triggered by stress at work. They were short, but there was nothing I could do to control them. When I felt one coming on I would go to the bathroom and wait for it to be over. Felt like a heart attack. I was advised therapy and meds. Didn’t do the meds. Did the therapy, it didn’t help and I just had to deal with it. Over time the attacks were less frequent. Since my late 20’s they’ve been in remission, but there’s nothing I voluntarily did to suppress my episodes.
If you're having a non-voluntary (autonomic) physical symptom, you should really try to determine what triggers it. A daily activity (including stressful activities) log is a useful tool for that.
That would be a medical condition totally different from everyday anxiety. Much in the same way that clinical depression is totally different from being grumpy now and then.
If you're prescribed meds for the condition, you should take your meds. But, just like trying to isolate triggers, it's important to keep a log of how you react to the medication so your physician can dial-in the dosage. Psych meds are definitely not one-size-fits-all.
Just like depression however, when most people say the are depressed, they mean they're in a grumpy mood. When a person says they have anxiety, what they mean is, they're worried about some particular thing that happened or might happen to them.
That type of non-clinical depression or non-clinical anxiety is very much a voluntary state as opposed to an autonomous reflex and is very much under the person's control.
