I have asked several doctors and all replied with "that's normal for this condition".Yet i don't read much or anything about a similar pattern 

I have GAD with panic disorder and it started to spiral again around 2 weeks ago. Started Lexapro now to give it a try. (Did Sertralin/zoloft 2 years ago in a similar bad situation) but want to try Lexapro now.

My issue - after waking up with a horrible depression and anxiety attack every day, which goes away after roughly 10 minutes and a coffee, i am functioning the whole morning until noon approaches. I feel it building up and from 12:30 on such extreme anxiety with all kinds of horror thoughts + 2-3 real panic attacks hit me. This goes on till roughly 3 pm then the horrible thought spiral subsides slightly at least. 

My only explanation is that cortisol spikes at that time but is this really something others have as well ? 

When i had that the first time 2 years ago, i got rushed to the hospital. Same time. Can it really be my brain has logged this as extreme dangerous situation and does not let go since ? I had remission last summer, however needed to lay down the exact same time due to general exhaustion.

It's not from the SSRI, it started way before.

The bout is so bad that no rational thought, mind technique, breathing exercises help. Feel i am going insane, was close to driving to the psychiatric ward the past days.
