What to do if i cry immediately if i am stressed knowing that in some situations i don't want to cry infront of people...how to reduce crying ?

Stress inoculation: Note all known situations in which you feel anxious. Work on developing skills for relaxing and rehearse them until you can pull them up with little effort. Skills like breathing techniques, wearing clothes in which you feel empowered, learning other skills such as tapping and others (which you can learn from a therapist, also a possible plan). Melds could help. Your doc can help here. Plan.
