I think thats just GAD really, you end up worrying about everything & nothing. Even when you are not worrying you are still anxious because your subconscious just keeps pushing out the symptoms. Thats why I think CBT is lacklustre if it doesn't also look at behavioural elements to alter your perception of symptoms.

Have you been on Citalopram long? It took me about 3 months to get a better sleep routine back in but that was mostly due to taking Zopiclone for 30 days straight because my GP didn't tell me to cycle it every other day! Something the crisis team told me in their follow up visit. So, I had problems withdrawing from it.

Have you considered magnesium? There are members on here discussing how it has been useful to them on the Natural Remedies board and there is a magnesium taurate one on the GAD board.
