Creativity

I say, do creative people get inspired by anything and everything all the time? Is it that easy? I thought i was creative until i had soo much being expected of me...now i can't think. It's not good. I don't feel like im creative anymore...My writing teacher expects me to come up with a new peace of creative writing everyday...im sorry i dont work well under pressure...Is that bad? Oh man im really not feeling too great lately... Inspiration minimal on the things that matter most...
