It might be hard to get rid of anxiety completely, but you can certainly do things to reduce your symptoms. The videos you guys shared are good. There are many like that on YouTube, but I like the personal approach more when dealing with anxiety.
Talking to a therapist is probably the best way to deal with it. Still, many people aren't comfortable with talking to a therapist or don't have the money to do it.
If I can make a contribution to this discussion, then I would recommend the
Calmer App. It is an app that is still in beta version, but I hope it will be officially launched soon.
It has everything you need to train self-control, including guided meditation, instant anxiety relief tools and cognitive behavior therapy methods. I use it daily since I found out about it
