I’m not a doctor and I don’t suffer from anxiety (more than the average person) so I’m just speaking from my own life experience.
I feel like the biggest thing for anxiety is to calm the mind. I believe the biggest thing you can do to have the mind be more calm on a permanent level, is to get into meditation.
Meditation does wonders for quieting mental chatter, which in turn, gives us more mental clarity, and an effect of that is, life kind of “slows down” You are more naturally going with the flow and things like anxiety, frustration, anger, helplessness, etc... will happen less and be greatly improved.
This world has a lot of stimulus and we get caught up in it. We have to constantly work to decompress mentally and “zoom out” and not get so caught up in this shyt.
