Nervous

So tomorrow I go for my first counselling session. I am feeling scared and nervous. I honestly don't think any one is bothered. I feel so alone. My heart is pounding already. I just want a good nights sleep but I know that anxiety will keep me up most of it. I have been up early and kept busy all day but even though my body is tired my mind is going ten to the dozen. I'm sick to death of the constant noise in my head. I have tried all of the tips to sleep but nothing works. I don't want to relay on sleeping tablets as I have enough vices. I have been to counselling before but I have never felt this ill. I have so many upsets at the moment, I don't know where to start. When I go do I start at the beginning of my life (to which some issues relate) or do I start at this recent upset? So much to say and one hour to do it in. I think the counsellor will need to book in a full two weeks nine to five just to get my back ground. Please let me sleep tonight, Please let my mind quieten and rest, please let this ball of hurt in the middle of my chest ease, just one nights good sleep so I can at least organise my thoughts for tomorrow. please xxxx
