'I want to heal and I don't know how' Listener question

You speak often of doing the thing that scares us to show us where the 'self' is showing up.  What if I have been doing the thing for over a decade and it's led to horrific anxiety (panic attacks GAD insomnia) It's been a decade now.  I worked for two decades without any problems and then as soon as financial insecurity showed up I had one panic attack and boom, my life forever changed.  I feel like I'm in the deep end and there's not the opportunity to go in slow.  The program still seems to think this is the way I have to earn a living as everything I look into comes to a dead end.  I also know that I worked so many years without this issue, so why not again? I know that my brain has changed and this system is looping around on the same neural pathways that have now been created.  Does it take time for the systems' auto pilot of body reactions to change.  I feel like my nervous system is so revved up all the time that it's stuck in my body and this is now my life, which I want to heal, and don't know how.
