My T tells me to try and not feel overwhlemed by emotions just sit with them and be interested in them rather than trying to get rid of them / block them. Also I am encouraged to do mindfulness, but easier said than done when my head is in a spin - but working on it - I have found Pema Chodron's books helpful - I am also exploring the possibility that I just tend to feel emotions more intensely than most people, so again try to reassure myself when I am feeling panicky that it is OK, than I am OK and it will pass.
