"i never comment on these this but i feel this website sharing positive experiences helped me a lot. i had my first panic attack two months ago after a night out. weeks of having 3-4 panic attacks a day and massive levels of anxiety followed. i tried to carry on with life as normal going to work, etc. and started cbt, which helped me establish it had started due to increased stress from work. i struggled to get on trains, tubes, eating in restaurant&#039;s, shopping...pretty much every day to day task. when i was put onto cipralex and for the first four weeks i had high levels on anxiety, headaches, disassociation, tight chest, chest pains. now on week 5 on lexapro i am feeling much better and can do everything i did before with only low levels of anxiety."
