im curious if anyone who was diagnosed with anxiety disorder has ever dealt with extreme anger issues? Out of nowhere i have found myself uncontrollably angry. I am having moments of extreme rage and find myself staying up all night with anxiety attacks and sleeping most of the day. i keep fearing brain tumor as i am feeling outside of myself. Please reassure me that these feelings are normal symptoms of anxiety. I am not taking any medications other then ativan 0.5mg when i feel the need to.
your symptoms are normal with anxiety. feeling outside of yourself is called depersonalization and its not harmful, but feels weird. ive had it many times. it’s your brain‘s way of trying to protect you from stress and anxiety by blocking things out. Feelings of anger with anxiety are also common . you could have some underlying depression going on also. It would be a good idea to speak with a therapist who can help you sort this all out.
listen to meditations for anxiety, anger, sleep, etc on you tube. i do this every night and they are great. 
I also have a panic disorder and uncommonly (but not rarely) experience flashes of really intense anger, almost rage. I never linked the anger to my panic attacks, but I suppose it would make a certain amount of sense for the way the mind and body experience fear (snowballing into panic) to have a similar reaction to anger, fueling into rage. As long as you’re not hurting yourself or others during these anger events, though, I wouldn’t be too worried. It sounds like you’re otherwise experiencing very typical symptoms of anxiety, such as healthy anxiety and derealization. They are very uncomfortable and disturbing sensations, to be sure, but not abnormal, and they do go away with time.
I personally have not really had the anger part, just the anxiety and panic attacks but my uncle went through this and finally went to see a physician and he had a form of bipolar, mood disorder and they got him on the right medicine and hes been back to his self without the anger for years. Just thought I would mention if, not sure if you may have already discussed it with your Doc yet.
