I think I have a mild anxiety disorder.  Everytime I am in the elevator, no matter it is filled with people or not , I will have this thoughts that something bad is going to happen. I will start sweating,and  my heart will beat faster than the normal which causes chest pain I guess ?  The symptoms will be worse when I'm in the elevator alone.  Luckily , I don't have any panic attacks. Once I get off from the elevator ,  I will feel fine again. I will start sweating and my heartbeat will slow down again. 

This may be because I was stuck in elevator in Toronto. That was my first time stuck in the elevator. I was really scared. When the elevator is fixed , I was so afraid that I didn't get into the elevator again.What I was suprised was that my mom wasn't even scared at all. =_=. I felt like a coward. She got into the elevator again While I  I had to find my way to the escalators and reached the 10th floor alone.
