Are your colleagues annoying? Does your boss demand too much? Do you feel provoked? Naturally if this is the case, take long deep breath before making any wild assumptions or accusations; if you want to maintain a good working relationship with others. Eventually you'll manage to overcome your problems and be able to tackle any especially demanding tasks.
Love and partnership
You're not behaving very diplomatically and your lover is feeling the full effects of your dismissive attitude. Be more considerate and allow others to express their point of view as well. Your stubbornness and bossiness tends to bug your partner and they feel exasperated. If single approach matters less-hastily, thoughtfulness often gets you further than obstinacy.
The best way to reduce your current stress level is through physical exercise. Preeminent activities are those that foster stamina and help you return to a feeling of inner balance. When did you last take a long walk? You should avoid sports that demand interaction with others. The risk of getting into arguments is too great and only brings along with it additional stress.
