If your job stresses you out (in the crying before work, pulling your hair our kind of way) then it’s not the right job. If you’re working as a biochemist but you dispise analyzing and researching, it’s probably not for you. If you hate what you’re doing, it’s going to feel stressful every day, even if your doing a great job. We’re only human, sometimes we make the wrong choice. I truly believe that, whatever higher power you believe in, constantly tries to drive you towards your passions. If more people did what they enjoyed, the world would be a much more enjoyable place to live.
Be persistent in finding your passion and working towards having your life revolve around that passion.
