I feel pretty certain you should not just go back to work, Sophia! Whatever is telling you that, don't listen.
I am telling me that! I have so much vacation that I am going to lose that I would rather work a couple hours and do intermittent FMLA to burn the vacation than have no contact with my main source of other people to talk to and mental stimulation in person! Instead I have a gatekeeper boss who told everyone to go through her and she would decide what I needed to hear. I heard this when I reached out to my work friend Bob he had been told not to contact me directly. Now she has texted me “ Would you be okay if a group of us (your friends) worked with you to understand your changing needs while you’re out and set something like a schedule to make sure we help as much as we can?”. She is a hospice nurse and it is rather disconcerting before I know the plan from my actual doctor.
