I know from some of your previous posts, that previously you'd been in an extremely stressful situation for a long time ?.
I'm not a medical expert, but from suffering from my own anxiety problems for a long time and my own research I've done, as a result of there being very little help out there, I believe a lot of chronic anxiety problems are caused by the overproduction of the stress hormone Cortisol.
It's produced under normal circumstances as part of the waking up process, but is also produced during periods of extreme stress, as part of the bodies "'fight or flight " programme.
However if you're placed in an extremely stressful situation for a long time, you're body overreacts to every little thing that worries / stresses you out and produces too much of it, leading to anxiety and all the symptoms you describe. You're almost in a " loop " of anxiety.
Have a look at CORTISOL and see what you think ?. It sounds to me as this is what is happening mate.
There are various things that can help - avoid caffeine and alcohol. Excercise, CBT, take zinc, magnesium and vitamin b. There are natural sedatives such as Valerian Root which can help.
I bet you also sleep badly too and wake up with a bang, thinking all kinds of mad things and feel anxious from the moment you wake ? ( too much Cortisol in the system ).
The problem with anxiety, is that it's so hard to treat, that it's almost ignored to an extent by the medical professional.
Hope this helps ?
