Stressed vs Pressured

Somehow I feel stressed over work, but not pressured. I know, this two words come hand in hand with each other. But what makes me think I'm stressed but not pressured?


Here's the definitions of these 2 words from AskOxford.com:

stress
• noun 1 pressure or tension exerted on a material object. 2 a state of mental, emotional, or other strain. 3 particular emphasis. 4 emphasis given to a syllable or word in speech


pressure
• noun 1 the continuous physical force exerted on or against an object by something in contact with it. 2 the use of persuasion or intimidation to make someone do something. 3 a feeling of stressful urgency. 4 the force per unit area exerted by a fluid against a surface.



Somehow, for the first time, I felt the two words are different from each other. Here's my own definition:

stress
• stretched out, tired, exhausted, sleepy

pressure
• can't breath (but not suffocating though)

Simple huh? Coz I'm a very simple person. Hiakzz hiakzz hiakzz.
