I actually prefer to be busy because I hate having spare time (not that I have much anyway). I know that's not a good thing but it's how I've lived most of my life. My lifestyle as a carer obviously contributes to how I feel but I have always had an anxiety disorder so it has just continued throughout my life. I accept it and manage it as best I can-the relatively recent death of my Dad has affected me badly though and the agitation is worse now but I'll survive...as you will.
Just carry on writing your feelings on here if it helps? I admire you for your yoga expertise-I'd need a general anaesthetic for that!
