I don't know if I have actual flashbacks...I have moments where I feel I'm in the thick of it but I always know I'm not. Reminding myself I'm here and not there wouldn't be necessary. I replay them and see what I can learn from them if I'm able, or talk out my feelings with someone, or give myself a moment to grieve over it all and remind myself it wasn't my fault and I didn't deserve it can help. Other times I distract with whatever is working at the time. Books, movie, puppy tickles, hot bath with epsoms. I think I kinda hyperventilate sometimes and then I sit with my head kinda between my knees and focus on breathing while hubby rubs my back. Whatever works. I will consider the tips you suggested too. I'm sorry you have these so severely. (((Hugs)))
