I have generalized anxiety disorder but my case is very severe, I wake up anxious every day and the anxiety never goes away, my muscles are always tense,  my breathing is very accelerated, and I can't focus on anything, I literally feel like this 24/7, I can't recall any moment from the past few months where I didn't feel anxious. As a consequence, I'm always physically tired since my body is on alert mode all the time. Is anyone else here suffering from this kind of anxiety? If so what do you do to manage it?
