Why am I stressed all the time?

Why am I so stressed out? Job, looking for a job, bills, partner, blah blah blah…etc. I’m sick and tired of my cortisol levels being at an all time high. I always have a feeling of impending doom – like the shoe is about to drop kick me into an even higher fight or flight mode. It’s as if I can’t take a breath. A long, deep, satisfying breath. I wake up every day feeling like I’m missing something – but what exactly?
