After my last super-stressful job (event planning), I evaluated what I was looking for that would NOT stress me out. I started talking to friends and networking in a casual way. Saying things like "I researched the burnout rate for my industry and the ceiling seems to be 5 years. I'm looking to change careers before then, so that I'm still effective and engaged" makes it sound professional and well thought out.
I found a job that would be much lower stress for most people, a work-at-home-gig where I had few deadlines and it fit my personality. It did offer excellent benefits.
Six months and a prescription for anti-depressants later, I realized that it wasn't the 'job' that was stressful, it was the environment. I loved the charge of pulling off a successful event, loved the organization and logistics. I hated being bully-managed by a near sociopath with anger management issues in a misogynistic, xenophobic, and homophobic company. It took me a change of industry to realize what I loved.
I put out feelers and now have an excellent job in an excellent company with a stellar reputation and great benefits.
To summarize, start asking around. If your cousin's roommate is in your field, ask about their work environment. Mention that you're looking for X, Y, and Z in your work environment, and do they know of anywhere that meets those criteria? Go to job fairs and ask the rep about their specific work vibe. You can find something you enjoy in a good place. Good luck!
