Finding the balance is really hard, I feel you. When I was a full time summer worker and full time student last summer I was ready to break at all points and had little to no social or home life. Thankfully work filled social for me, but I was still left with no energy at home, but finding my routine helped me a lot and making sure to schedule at least one fun thing a week made me have something to look forward to. Also giving less than my 100% at work helped me, but that’s not best practices
I work 60+ hours per week. Some things that help me is bringing snacks that I can eat throughout my shift (and I bring dinner to eat during my meal break). I also bring Gatorade to keep my electrolytes up. And I ask for physical accommodations because I am disabled (a chair when needed, meds and food, etc). That stuff keeps my physical energy up. I bring my headphones so I can talk to my boyfriend during my hour lunch break, and I bring a word search so that I can do that on my breaks.
Sometimes naps help, even just hour/hour and an half ones you take directly after getting back to get yourself in a different mental space for the rest of the day. Like I just got back and 5 and slept until 6:20pm, and now I’m rested enough to actually enjoy the next 6-7 more hours of my day
That stuff helps fulfill my social needs and keeps things bearable. To keep my brain stimulated, I try to ask for new tasks if there are any. When I’m just stuck in the same monotonous tasks, I try to have lively internal conversations with myself or make elaborate plans for my future.
