Frustrated With My Camera

I must say that these days, my camera is not my best friend. No matter what I do my pictures are not turning out right. Most of the time they are blurr or grainy and it is driving me nuts! I don't remember my camera having these issues before ... did I mess up something with the settings? I think it might be time to start looking for a new best friend, the only problem is I don't know what I want in a camera these days. I like the convience of point and shoot but those big fancy cameras with the different lens look so cool!
