All of the above, to some extent 🙂
All in all though, counselling and psychotherapy have been the greatest supports I've ever found for dealing with anxiety. Chilling out with a nice bath and some music, which I really love, is very nice and soothing, but to get a firm handle on the causes of my anxieties and to actually tackle their roots and effects in a lasting and truly, deeply transformative way, I've found nothing better than a good psychotherapist.
I wish we all got some kind of emotional support from our diabetic clinics. As a rule of thumb, if you've been feeling upset for more than two weeks, it's worth trying to see a counsellor or therapist right now; it can take a lot longer than this on the NHS. If you look around you can sometimes find low rate ones from ?5-12 an hour if money is a concern.
