Me again - I forgot to mention that as regards the anxiety Lexapro has been pretty good. I feel that it is still there, there are emotions that are being masked, but it is much easier to get on with my life, only after a month and probably before it has had its full effect.
I have also found that some persistent, unwelcome thoughts (I think I was a bit OCD) are much easier to control. I was obsessing about difficult things to do with jealousy, sex and relationships - they were starting to intrude into my life, especially at work or when I was trying to sleep, and this is much better now. The thoughts are still there but don't come as often, I can push them down more easily, and the issues themselves don't seem as important.
