FT WFH Home/Work Separation Advice

I recently started a fully remote position (two months ago). I was previously hybrid (two days in office three days at home), and I have recently felt like I am having a hard time not thinking about work on my off time. I didn’t have any issues with this with my previous position, and I am wondering if part of that was due to culture of the department, or if it was the two days in office that helped provide separation. Previous position was definitely a more lax vibe in a way, partly due to my manager being a brand new manager and not paying much attention to me. There are more deliverables and expectations with this job, but I don’t feel that it should be overwhelming, and yet I am thinking about work almost nonstop.

I do luckily have the option of going in office if I would like to, so I think I am going to try going in one (or more) days a week to see if that helps. Generally wondering what other people’s experiences with this have been, and if there are any tips that you have found helpful when wfh full time! A few of the other pieces of context that might be relevant are that I live alone in an apartment, so its easy to feel isolated, but I make it a point to get out of the house a lot, whether thats walks with my dog, or going out with friends, etc. I’m also at the beginning of my career, I worked full time during my undergrad but this is my first position since graduating, so I feel like part of it might just be trying to get a feel for the culture while also being remote. Hopefully this provides an idea of some of the factors that I think might be playing into this, but happy to provide more context as well.

Any thoughts and tips appreciated, thanks!
