The struggle of quitting my job

I’ve been at my job for 3 years and have been unhappy for a long time. The reason I’ve stayed this long is because I know the job (even though it’s a vet so every day is different) and the pay for my position compared to anywhere else is above average..

I’m also trying to buy a mobile home for my property this year and I’m worried that changing jobs would be a bad idea since I’m pretty sure they will check if I’ve changed jobs and pay and stuff. My husband just got a new job as well and is in school so he has his own stuff going on and I hate to bring my stress and anxiety home to him about my work situation.

I actually feel stuck between a rock and a hard place…
