Sweating A LOT while trying to sleep!?

Maybe it's stress from my brother being in the hospital but my period came almost 2 months late! Now on my period I'm trying to sleep and I'm having mood swings getting soooo hungry and it feels like my body is on fire I took off blankets and all my clothes for the most part and nothing has helped D: I'm seriously tired as hell and have finals tomorrow! Why am I sweating all over out of no wear? I feel so restless I almost want to cry, I haven't slept in 2 days :(
