How can I learn to confront anxiety provoking situations?

One step at a time, in my personal experience! Perhaps make a list of things that are challenging to you. Then start with the least confronting on the list. Be kind to yourself and acknowledge your successes along the way. You can then make your way up the list to more challenging things, but take your time with it and don't rush. This strategy helped me immensely with social anxiety.

Jump in with both feet. Hesitation allows for missed opportunities. Sometimes when the water feels a little too cold when you dip your toe in, if you jump in and put your head under the water you realize that it's not that bad.

Sometimes confronting anxiety-producing situations is as simple as practice or even just edging toward a goal. For someone who cannot leave home just the act of putting a hand on the door is empowering. Someone else with Social anxiety may benefit from going to a coffee shop with a trusted friend. Therapy can also be of great help, those with GAD or PTSD can greatly reduce their discomfort when they reach out to a trained professional. In particular, Eye Movement therapy has been shown to be extremely effective at reducing triggers for people with PTSD even when it is considered complex PTSD. Above all else, self-compassion and self-care are vital to facing the challenges of anxiety when we are unfed we cannot exert the kind of mental energy that overcoming obstacles requires.

I would Accept and understand the anxiety provoking situation for just accept it for what it is and then breathe. I would Think logically about how I can deal with the situation and then deal with it based on fact rather than emotion. Step outside of the emotion of the situation and just make reactions or decisions based on facts about the situation and not emotion. Understand that sometimes people enjoy the negative reaction and don't allow myself to be controlled by other peoples emotions or intentions. Confront anxiety provoking situations head on rather than avoiding because sometimes that makes things worse.
