Dealing with work fatigue

I work full time in an office with one day a week at home. My job made the exception for me due to my long commute as others don’t get to work from home. It’s a good job but it’s getting to the point where I cry most days on the bus home as I'm so exhausted. I don’t feel like going part time or reducing hours would make sense as it really is the commute (1.5 hours each way) that’s getting to me. I’m thinking of moving to New Zealand, Australia or somewhere in Europe to try get a better work life balance but I’m worry about the issue with MS in the working holiday visa application as I’ve read some things I’m quite torn and would love to hear if anyone has similar issues in work or moved for a better work life balance
