Just a little share in a hope it will help someone..
I am increasingly finding better coping techniques for my anxiety which is still there but much improved since last year. Haven't had a panic attack for a well over a year and with the help of counselling I am able to stop or slow down my anxiety with a few tricks.
Something that I stumbled across was gregorian chanting music, freely available on youtube. For whatever reason my anxiety tends to creep up on me at night and it seems 10 x worse than during the day. Putting headphones on and listening to this has been very soothing, I don't know why, probably the repitition and tone of the male voices. I also listen to this on public transport when I feel quite stressed.
Worth a go maybe?
