So in order of my symptoms: tired, cold, not hungry, head ache, paleness..?

Am I sick or something? around the end of school I started getting sleepier and sleepier, but I fell asleep around 11 and woke up at 8 so I don't think it's lack of sleep, then went I went home I laid down but I started getting really cold even though I had two blankets on me. Around 5:30 my mom had me come up stairs to set the table, and I didn't eat cause I just wasn't hungry. Well I was still really cold so I went to take a shower when I looked in the mirror and my face was pale, like really pale and then I shook my head to see if I was starting to develop a head ache and I just hadn't realized it cause I was so tired and sure enough I had a head ache. So tell me, am I getting sick? If I am should I stay home from school tomorrow and rest, cause I'm having a party for my birthday Saturday which I really don't want to miss! Thanks for help
