As its Sunday and my GP is obviously not open until tomorrow

On Tuesday night I had a night shifr (I’m a registered nurse) and had to go home early because of vomiting diarrheal and the worst body aches I’ve ever had in my life, like period body aches x10000099. I was obviously off for the Wednesday night shift as well, and felt better by Thursday. I then phoned to say I was ok to do my Friday night shift, and felt fine until again, like 2 in the morning

Started feeling incredibly nauseas, extremely tired (more than is normal for night shift), quite breathless (am usually breathless anyways but this was more than usual) and my body just felt “heavy”? As if it was being pulled down? Don’t know how else to explain it.

After going home after night shift (finish at 7:30, got home at 7:50), I couldn’t sleep until 9. Woke up after 30 mins and vomitted again, and since then the nausea hasn’t really gone away? Like it’s ALOT better but still kind of lingers there? Appetite is also very reduced and am extremely tired
