I've suffered anxiety all my life, genuinely. From first conscious memories I was always worried about something (early years, burglars, fires etc, latterly, health anxiety).
Medication obviously has helped, as has therapy.
Things like time and space to do absolutely nothing helps me. I'm a full time, stay at home mum, so one day a week (when ex has my DS) I crochet, watch rubbish on television, go for a walk, have a bath, read, use Pinterest, play mobile games, colour with adult colouring books, buy myself a nice lunch and a coffee. I adore those days as the rest of the time it's balls to the walls type gig.
When I'm feeling super anxious I often distract by scrabble, or something mindless on TV that I've watched hundreds of times that has fond memories.
It's horrible, and I hate being like this - but I've only ever known it, so I've become reasonably adept at counteracting it.
