bubblysqueak, hello and welcome, you're among people that understand!
Tips? Don't try to cope alone! If you need support talk to your friends, partner, family, people care and I have never faced stigma.
Understand - find out about anxiety. Loads of stuff around - Anxiety UK, Anxiety United are good places to start and I've just been recommended a book 'Breaking Mad' (I do have a library full of other things too)
Keep up your mindfulness and download apps to help - there are loads
Think of some distractions that may work for you - it doesn't matter what, just stay busy - jigsaws, puzzles, knitting, fiddle toys, online shopping, meal planning
Try not to spend too much time alone when you will be going over your thoughts
Try relaxing smells eg aromatherapy pulse point oils for relaxation
Some people have had success with Rescue Remedy and/or Kalms (although many of us here are on prescribed medication)
Hope that helps x
