Going back to work

I have to go back to the office full time soon and have enjoyed my time working from home. I am feeling resentful and scared about going back because my job can be done from home and I think my boss is being selfish having us go back when COVID is still high. I’m trying to be okay with this and can use some help with neutral thoughts. I keep thinking: work is work, work exists and then I can’t help but think: I need a new job (for this and other reasons).
