8+5 and feeling awful

hello

I feel awful. I got over Covid a week ago and still I have awful body pain, all day severe nausea, very hungry but the thought of and smell of food makes me very sick.. can not sleep at night or get anything done during the day my body feels so weak.. only comfortable position is lying flat on the ground with an ice pack to help with the nausea. Does anyone have any tips? This is unbearable for me.
