I hope you do coax yourself into push yourself out of the safety bubble solely to make it larger. Give yourself options for when you need or want a change. And yes, it is very difficult. Anxiety has a fun way of shrinking your world.
Sounds like you want to push yourself to new things in your life, but are scared of what that means in your life? It'll be up to you, with your anxiety, but pushing towards those things may help with your anxiety.
