How To Overcome The Stress And Tension During Work?

The patient (my daughter) is 25 years old working, a software engineer working in a stressful situation. She's been stress- & anxiety-prone since childhood & was taking anti-depressants during three years of college. Now, three years after college & working, she quit a project that she thought was irrelevant, but faced pressure from placement managers to stay put. She finds just about everybody in her company intimidating & always imagines worst-case scenarios. Finds it difficult to go to work, face placement managers at work - feels a build-up of tension when entering her work premises. Having taken medication once, she's also exteremely averse to going through medication again.
