Sorry to hear that you are getting panic attacks Donna, they really are horrid. I think if you accept them for what they are and not try to fight it, they are not quite so scary.
I went to my brother's 50th birthday party yesterday, and since my SAH I seem to get overexcited and then cannot calm back down again. I had a great time but then when I got home my brain seemed to be whizzing, was still awake at 3am and felt like my head was going to explode with all the thoughts whizzing round! I tried my meditation and it didn't work! eventually fell asleep at around 4 am and woke up at 6.30 with a splitting headache. It will take me a couple of days to wind back down, just from going to a party, it is so frustrating. Anyway, all sorts of scary thoughts go through my head in the middle of the night and I just say to myself " Thankyou mind for that thought" and then think about something else, because that is all that they are, thoughts that are just passing through my head. Hope this might help
