Thanks Miles. I really messed up last night because for some stupid reason I decided to stay up til midnight. Then I woke up at 5am anxious that I wouldn't get enough sleep! So then I couldn't get back to sleep properly. I've always found it hard to motivate myself to go to bed - before this anxiety episode began I used to sleep from midnight to 7am during the week. I shouldn't really do that any more - if I'm only in bed for 7 hours I can't afford to lose 2 hours through worrying! I'll have to try and get an earlier night tonight.
Evening update: Due to the tiredness, I felt more anxious than usual. I was busy at work though and this helped to keep my mind off the negative thoughts for most of the time. When I got home in the evening I felt more relaxed but due to the tiredness I felt a bit fed up. I was supposed to be going out for a meal with my social club tonight but it was cancelled. In some ways it's probably just as well as I think I would've been too tired to enjoy it properly.
Tomorrow it will be exactly 2 weeks since I started citalopram. I didn't feel too bad for most of last week and the weekend, but I think now that I've gone back to work my anxiety levels have gone up again. Thankfully they're still not as bad as they were 2 or 3 weeks ago though. Sometimes I worry that I'm going to go back to how anxious I was previously though, and that scares me!
