You have a lot of money in savings, and a career in a high-demand, well-paid industry. You could be better off, and it's good to strive fore more security, but no matter how secure you are, there are always going to be reasons to worry.
Learning to cope with anxiety is a must-have skill, in my opinion.
One of the first things my therapist introduced me to was called the ARC model of emotion, which stands for Antecedent (whatever is happening just before you experience an emotion), Response (how you feel and what you do) and Consequence (the results of your response).
Basically, by taking note of what is happening when you are anxious, you can start to identify what is triggering the anxiety. Simply identifying the source of your anxiety goes a long way toward reducing its hold on you.
