Stress at work how to overcome it? Should I leave early even though I gave 2weeks?

Well I started a new job last week. I didn't like it that much and decided to give 2 weeks.( I wanted to be professional) I want to focus more on my studies.Anyway, I am starting to have real anxiety at work. Today I only stayed like 5 mins before I started to cry. When I cry sometimes it gets hard to breathe. I have a pretty busy schdule next week and I am not sure if I can make it.I don't want it to ruin me getting other jobs. I was stressed out at my previous job as well but not this bad. It makes me feel really dumb and all. Thank god everyone is really nice to me there. So should I quit now or try my best and stick it out if I even can? Thanks for your input this is my first question :)

You only started last week? You need to take care of yourself first! You should quit today if it stresses you out that much. I would suggest being upfront about it. Just tell your boss you thank them for the opportunity to work there, but you can't finish out your two weeks.

You would be wise to stick this one out. Although it may be hard, it is to your advantage (for multiple reasons) to do so.

Not only will you prove to yourself that you can get through difficult situations (this is VERY IMPORTANT), you will also be able to leave on good terms.

"Burning bridges", in the world of work, is never a good idea.

Hang in there,

Before you change jobs or careers, try tuning up what you've already got. It isn't easy to jump from job to job鈥攏or is it always a good idea. Sudden career shifts are often painful and financially disastrous, as in the case of the geologist who turned an $85,000 career into a $12,000 job by selling life insurance.
Where career is concerned, incremental change鈥攃hange in small steps鈥攊s usually best.
Before looking across the fence, look in your own back yard.If you're contributing and able to continue growing, if you're adding value, if you're energized and interested, then time in a job is irrelevant. There are always ways to grow without leaving.
Some people change careers to find the perfect job. That may be possible, but no job is ideal for long. Even the best jobs must be reinvented, because your favorite boss leaves, the company merges or suffers financial problems, or your have conflict with a co-worker. All jobs require care and feeding.
So why not start right where you are? If that fails, you can always look elsewhere.
Jobs usually fail around personal relationships, and this is where you can do the most productive work. Fight the tendency to run away, to think "it's them," instead of "it's me." If there's a problem, realize that without knowing it, you may be part of the problem.
It's difficult to be objective about yourself: that usually requires outside intervention. Find a friend, minister, psychologist, or career counselor to serve as a sounding board.

Try to improve relationships with everyone in your work world: your boss, peers, subordinates, consultants, vendors, and customers. Talk with your boss more, and attempt to resolve outstanding issues with co-workers. Change your attitude. Apologize, if necessary, and become more assertive, or less assertive, whichever is called for.

Jobs or careers change sounds like a lot of fun, perhaps an easy way to fix problems, but proceed with extreme caution: before you attempt a 3-1/2 gainer off the 10-meter tower, check to be sure there's water in the pool.

Try your best and stick it out if you even can! If that fails, you can always look elsewhere.

Good lack and be strong!
