Working away anxiety advice

Hi everyone im new here, I have anxiety from working away. I do 2 weeks of work straight and I get really stressed and worry about my partner at home alone. I have an exit plan to go back studying but thats in another 6 months. I find that even when I get home I still think about work and how ill have to go back. Its worked its way into my daily life where I worry something bad will happen to my partner or I just can't relax or find motivation to be productive with my spare time. I'm just not sure how to change this, how to stop feeling like this.
