question: Hello doctor, I have been experiencing what my mother says is a panic attack, but I am not sure because I only get racing thoughts, my heart races or beats really hard, and I feel shaky like I might cry (no other symptoms). I read that panic attacks peak at 10 minutes, but I feel this way for hours and it keeps me up at night. I have no previous problems with mental health, and I think it is only a fear of the dark keeping me up. What should I do?
