staying in foriegn country

Hello there.

I am from japan. I have suffered from panic disorder for 5 years .
There was a time i even couldnt que at the cashier in a supermarket. Thanksfully now im getting better.
Still need to take tranquilizers to have my hair cut at beauty salon , take a long distance coarch and etc.
One of my friends whos been in London for years invited me to visit there. It is a quite scary thing for me
taking a 12 hour flight from here. Though i have decided to take this chance.

Some say staying in foreign countries is streesfull so my panic disorder symptoms will get worse
and others say it would be good vacation and i will get more confidence with panic attacks if i could
cope with panic disorder in foreign countries.
I have a feeling that I will be ok. Though I worry when i think of what would happen when i have a panic attack and if it would last longer thant it does in japan etc.
I would appreciate it if anyone kindly recommand me some therapists who know well about panic disorder in London.
I have been a member of panic disorder patients group. and I am interested in taking a therapy in London.
I would also like to try aromatherapy . I heard it is good for mental disorders. is it?
I will be staying in Illford, essex .
I would also appreciate any advice about staying in foreign countries.

I heard panic prevention CD. it sure helped me a lot to understand panic disorder.
I feel like im going crazy when panic attack. i often have an panic attack when i m in the place where i cant move.
such as sitting on a chair at beauty salon, standing in observation wheel,etc.
In AWARE technique, its said "Behave normally and continue doing what you intended to do."
When i engage in something to use my body. it is easier to continue doing what I intend to do but
in those circumstances like i have my hair cut. i have nothing to do but staying still on a chair and it is very hard
for me . becasue theres nothing to distract my attention. if i keep tyring to use AWARE techiniques
even in those circumstances I will get to cope with it?

Thank you for reading . Excuse me for my poor English

Best regards
