Hi I totally sympathise,
panic attacks are dreadful to cope with, this book is useful -Overcoming Worry and Generalised Anxiety Disorder, 2nd Edition (Overcoming Books) Paperback – 7 May 2015
by Mark Freeston (Author), Kevin Meares (Author)
I find that these days I can't overload myself as my resilience is not what it used to be. We have so much more to cope with these days. I try to do positive thinking and do something nice each day, even something small like giving away my parking ticket made a lady very happy, which in turn made me feel good for a bit. Sounds silly but it all adds up.
