Don’t feel good

I’m miserable. Today I woke up really cold. Goosebumps everywhere and I was shivering. I turned the space heater on fell asleep. Woke up was really hot. Been hot for hours now. Sweating all that. I took my temperature but I don’t have a fever. Why is my body sweating bullets and I’m not running a fever? I sneeze quite a bit. Idk what’s going on but I really wish this would pass bc I’m cranky and my bf brought me out to go food shopping and I’m just being miserable. I’m beat.
