Anxiety is a very common mental health difficulty.  Anxiety goes beyond ordinary worrying and can be very distressing and disabling.  People may feel constantly on edge, worrying that things will go wrong, or experience such severe bouts of anxiety they have panic attacks.  Panic attacks can be very frightening, and people may feel as though they might collapse or even die, although this is not the case.  Anxiety can be treated very effectively with the right support.
