The start of my anxiety was bad panic attacks. I went through all the physical symptoms (fast heartbeat, weakness, choking sensations, tightness in chest) and was initially afraid to leave the house after it first happened. Well, I didn't let it overcome me and I just pushed myself to deal with it. Among the physical symptoms, I had real bad dep/derealization that for the most part lingered the better part of the day. Also an inability to think clearly and a serious sense of impending doom. This has been going on for a little over a year and I see health care professionals regularly. Some have questioned a bi-polar disorder but most think its panic/GAD. I use a small dose (0.5-1mg) dose of ativan every few days. But my main thing is, now that I know the physical symptoms of anxiety, and have overcame them, I don't get them anymore. But I feel like its almost worst attacking me totally mentally where I feel like I go emotionally numb and can't think straight, feel detatched, question my existence, feel the impending doom, and this can last a better part of the day on a bad day, and several hours on others or more than once through-out the day... but no pyshical symptoms accompany this anymore. Anyone else have something similar happen?
