Hello, i have been suffering intensly since I was just a little girl as well. I still really struggle with it, but I can tell you the few things I do to calm myself down or avoid a full blown "realization" attack, as I like to call it. This is going to sound crazy but I find it very comforting to rock back and forth whilst talking our loud to myself, usually saying the same thing over and over pretty rapidly. I find this helps to keep my mind preoccupied, and usually all the activity will make me tired enough to pass out. It still doesn''t result in a good nights sleep if you have work the next day but it''s the best I''ve managed to do for myself thus far. I''m currently looking into an anti-anxiety medication, I think that would probably be quite helpful to those of us in this situation, although it would be nice to get rid of the problem all together! The only time in my life when I didn''t get the attacks on a regular basis or at least found them less upsetting was when I was practicing meditation daily. I''m not religious bur o find it to be an incredibly beneficial exercise for the mind and body. I hope you find this helpful and thank you fir posting as I was starting to think I was alone

good luck
*also when you are just starting to think in that direction, if you can, immediatly distract yourself by doing something else, tv can be quite effective for switching your mind off, or even something like solitaire. I actually play solitaire every night until I fall asleep to try and keep myself from thinking before sleep. Sexual activity can also be very distracting, although obviously rather hard to accomplish if you are already in that state of mind, but like the solitaire it can be a helpful nighttime routine to keep.
