I use aromatherapy. I use a diffuser at home and carry something like Lavender or Peppermint in my hand bag for an on the spot 'cool down' from anxiety or elevated emotions as needed.

I have a few strategies for bringing myself down off the ceiling like my 'anxiety tool box' which are mostly items that evoke all 5 senses.

As for the need to suddenly DO something I can relate very well. I am not working and I have noticed the more my moods become elevated the more bored I become. To keep myself 'interested' and busy I have started writing, pulled out my art supplies, and have even paid more time and attention to cooking. To get myself out of the house (and this was a huge step in battling anxiety) I found a casual volunteer position. Still, there are those times during the day I grow antsy and bored. I notice this leads to a higher incidence of irritation. It is work, yes, but you can win the battle.
