lower stomic and side pains

I really don't know what is going on. For the past couple of days (i will say a week) i have been tired out of my mind. i will come home from scgool and just crash anywhere. Along with that i am neasous. Anytime of the day and no matter what i do i will feel sick to my stomach at least once a day. Thaere is a pain in my lower right side of my stomach going around into my back. The pain is at its worst in the morning. and does NOT go away during the day. I have also been extrmely cranky and blowing up at my boyfriend, mom, and just people that get in my way. I think i am cranky cause of me being so tired but i don't know. i just moved to and havent found a new doctor. 8-|
