Stressful job

My question is in relation to unhealthy stress on a job. My job requires me to be at work by 6:30 am, and many times I can’t leave until 5:30-6:30 pm. I have a 40-60 minute commute in the am and pm. I try to get about 7 hours of sleep a night or else I’m an absolute zombie during the day. I dream of being able to take a power nap in the afternoon but this is impossible. Managing my time so I can get the sleep I need leaves little time to do anything else I might enjoy (reading, exercising, etc). Many days I feel like I’m rushing home to just take a shower, pack my lunch and go to sleep. It is expected in my industry that you put in 12-13 hour days in spring and summer. Is there ever a point where its ok to change jobs because the stress level is unhealthy and the job is consuming your life?
