I don't know what you are doing to help with your anxiety. One thing that helped me get grounded was this exercise which focuses on your physical environment. When you feel anxiety:
Name 5 things you can touch. (say it out loud and touch them).
Name 5 things you can hear.
Name 5 things you can see.
Name 5 things you can smell. (scent is very powerful and if there are certain smells that calm you, use them!)
Oh yeah, and remember to breathe. Gnosis reminded me of this many times. Deep breaths help a lot.
You are getting stronger and you are much stronger than your H.
