I have been suffered from anxiety for months. i keep worrying about work and things go wrong. stress at work worsen the situation. please help me.

Therapy should help: getting a good therapist who will be patient and work through the things which contribute to the anxiety will be most effective.

See professional: seek the help of a professional for ways to deal with anxiety and check some of the checklists here that include deep breathing, mediation, visualization. Be positive and take a positive approach and if you have faith, pray.
