New grad: how do I stop thinking about work when I get home?

I graduated in May of 2025 and started in the icu November '25. Quickly discovered ICU is not for me and transferred to medsurg/tele. Im working nights 3-4 in a row every week pretty much. When Im off im exhausted but struggling with sleeping, eating, cleaning, being a person basically. On top of that, every time I try to sleep im inundated with racing thoughts of work, I even have dreams about being at work. I don't know how to get past this feeling of always being "on" and im worried about somehow already burning out. Any advice would be appreciated, I'll try anything at this point.
