oh no becky
It's good you've got the CMHT lady today - at least this will be an opportunity for her to see you on a "not so good" day, as well as a good day?
When I'd had a rubbish night and I had an appointment the next day I used to comfort myself in the fact they would see how much this was affecting me without me having to describe it whilst feeling well!
I know that's not much consolation. It's totally understandable and the sleep anxiety is NOT the "stupidist" thing - it is actually a very logical thing.
You are a sensible person, you aren't just making this up. This sleep problem is a real problem. I know it feels like it will never go away, but gradually gradually you WILL get better. I am not fully there myself yet, but I have so many coping strategies now, and so do you.
I do fear sometimes that once you have sleep anxiety, do you always have it? How can you ever get "back to normal" - but the truth is we have learnt so much, have so many weapons now in our fight against it. I do believe that it is possible to be free of sleep anxiety.
FWIW I didn't have a great night either. Some friends came over last night and one made me a non-decaff tea without asking what I wanted and I was too unassertive and pathetic to say "oh no, I don't want that!" So I drank it and then was awake till about 1am.
You will be ok today. Tell the CMHT woman about it - hopefully she will be really helpfulx
