hello there - i am so glad you have been to your GP, that was very brave of you.
I have been on citalopram twice now, have beenon them over a year now. What you describe sounds like me - extreme anxiety making me unable to cope with every day life. Total rage one minute, utter despair the next.
I found that counselling was a bit hit or miss for me - it can be a bit wallowy. Some people benefit from cognitive behavioural therapy which focuses on how you cope with things, how you think rather than looking for reasons.
I found that the first time i took citalopram i didn't really have any side effects and they seemed to work straight away, the second time was harder and i was quite poorly, suicidal thoughts, the works.
I do get the vivid dreams, nothing scary but very very real.
Find it harder to orgasm
but other than that nothing. Doesn't really matterwhen i take them.
Here is a linkto a support thread that i post on, a few of us are on citalopram on there and it is good to know you are not alone.
Don't be hard on yourself - you have taken a step to get help, thats a really good thing.
