Sounds just like me. The flushes make me anxious and panicky as I feel hot, heart feels like it's racing( even though it isn't) , chills, adrenaline rushes and so on. Then if I feel anxious, I get more flushes as too much adrenaline sloshing round. I try not to worry which is which as they're both helped by calm breathing, refocussing my attention outwards and just being in the moment rather than worrying if they're ever going to stop. xx
