I am a 16 year old girl and my body has been acting really weird lately and I don't know what's wrong with it. I've been have really sharp pains randomly in my sides, my arms and legs keep going numb, and every time I eat I get horrible diharia. I've also been really anxious and stressed lately. I'm kind of a  hypochondriac so please if you don't know don't make me more worried about having something I don't.
