panic in night and on waking

[rooby]

this is getting me down again now, poor sleep from anxiety and waking in the night in a sweat and panic and also in the morning, my body and brain is so tired. It's like my adrenalin is constantly running. I am on lexapro which doc told me to increase. I have valium too but don't like to keep taking them, and they only relax my body not my mind.
I had a breakdown before and can recognise these symptoms but don't know how to stop the cycle, please help
