I feel really sick but I don't have a fever?

Since I woke up this morning and took my brother to work I have been feeling terrible. I am extremely sensitive to cold and feel like I have the chills. I feel nauseous spontaneously but then it fades after a second, so I haven't thrown up or anything, but the nauseousness is also accompanied with a slow dizzy feeling like I'm floating but my stomach feels like it's doing back flips. I also feel really fatigued and wasn't even able to finish my usual work out that I've done every day for, I don't know four months now? I have a slight headache, but no fever. I am about to have a snack, maybe it will help the headache. One other possible symptom is my eyes feel really dry and itchy and I keep sniffling but nose isn't stuffy (ew). I'm home alone so my mommy isn't here to take care of me lol. So, my question is what could be wrong with me and does anyone know what I should do to feel better? Going to the doctor isn't an option right now.
