I've been feeling depressed lately, and my memories of the time my mother abandoned my brother and I have been flooding back. I was telling a close friend about the time my brother and I had panic attacks the same day at school, and found each other in the nurse's office before going home. Not even a minute after I recalled this memory, my brother messaged me on skype asking if I was there and that he had just woken up with a panic attack. I was so shocked. I tried to comfort him and told him I have them too. My relationship with my brother has been broken for years, and he never comes to me with his emotional problems - let alone at this very moment specifically about having a panic attack. Has anyone else experienced a strange sort of synchronization with their sibling who has also suffered from the same trauma as you?
