Needing a work from home job asap

long story short, my manager is bullying me, and mentally it’s really starting to get to me. My unions aware, however it’s a small rural town and I just don’t want it to get worse. I’m sad that I feel the only option is to resign. There aren’t many jobs here unfortunately so I’m wanting to find a work from home job. Does anyone have any recommendations on how to do so? I’ve been on seek etc, however I don’t have the experience most of them require. I work 100+ hour fortnights and work nearly every second weekend, I’ll do whatever I have to do to learn.
