aftermath of panic attack

Hi my name is Victoria i am 41 yrs old. I am a very positive person, love life, make the best of every situation, and love challenges. 3yra ago i had a major panic attack. It was a HUGE blow to my ego,selfesteem and my whole life in general.After alot of reading, i saught self help after i threw away the anxiety pills that the doctor prescribed(do not like medicines at all) After alot of hard work I managed to get over it. I have a good psychologist that i go to on a regular basis who helped me deal with childhood experience)But I still feel that i need some help when I am in a big crowd....i keep looking around to see if there is an exit....and i hate driving if i know that i am going to be stuck in traffic.do not like to go places withiout my husband being present.
I am happily married...very healthy(except this minor problem ) excercise nearly evryday, do not take any medicines, and generally feel vary good about my whole life.
i feel that i need some kind of remedy that i can carry around so that if i am having an attack i deal with it psychologically as well as physically taking something. I do feel that some kind of homeopathy remedy will help me. I have read alot about homeopathy and i just ordered the first aid kit of 36 remedies to use for common ailments of members of my family.Can you please prescribe a remedy or remedies that can help my feelings of unfounded fear?
My famiy and i are going abroad in January and i am concerned about myself beeing closed up in the plane and of being away from home.I want to feel excitment at going for a holiday but this concern is blocking my happiness
I hope to hear from you soon
Thankyou
