I have many physical symptoms of an anxiety attack, but I don't have the fear. Is that usual? My heart will start racing, I will have shortness of breath, may become sweaty, muscles will feel like they are twitching, I just don't feel this fear that I keep reading about. Although, I do have to remove myself from the situation to feel better. And it's always suddenly. I have no idea the triggers. I recently was diagnosed with depression, which I've struggled with for 25 years, since my mother died. But 2 years ago when my sister died I was told that those things I do, is actually an anxiety attack. I always thought it was something weird that just happened to me. No big deal. But is embarrassing and I'd make excuses as to my odd, brief behavior. I'm just really curious about not having the fear component and if it's really anxiety or something else. Thank you.
