Answer:
By definition stress is when the the percieved demands of a situation outweigh the percieved ability to cope. So effectively you're only ever stressed because you think you're stressed, so just try to approach the situation in a more positive frame of mind. So say the situation was that you had a tone of work and a deadline to meet; instead of thinking "how am I going to do all this?" You think "is this all I have to do?". If you find it so stressful that this approach doesn't work, try venting your frustration by using a stress ball for example. This will help to deal with the emotions that occur as a result of the stress before then weighing up pros and cons, rethinking your approach, and eventually solving the problem that's causing you stress.
