does anyone else stay in bed literally all day ?

From the moment I wake up to the moment I fall asleep I'm usually always in bed with the exception of once or twice a week I go to the grocery store or to doctors appointments but other than that I get super dizzy from just sitting up. Thankfully my SO has been cooking for me and bringing food to me in bed because every time I sit up I started seeing little black dots and then feel like I'm going to pass out. My back is always hurting and when I walk I can barely feel my legs. Is this normal ?! Anyone else going through this ? I get so bored and it's painful in my hips/back  from laying down all day.
