I am truly overwhelmed by the response to my post yesterday - you are all lovely, lovely people for caring enough to reply.
I think I will need a little time to 'open up' to you all as I don't want to appear needy or whiney. For now I will say that I have a past record of depression, and though I think I may be verging on another bout, I really feel that anxiety is a bigger issue at present, though I have never been diagnosed with this in the past and am not sure if it's the 'real deal' or not.
I'm finding it difficult to sleep and about a week ago I started taking 'kalms' to try and relieve this, they worked a treat but now I'm getting twinges in my chest (I know there is nothing wrong with my heart), my thinking is not clear and my appetite is being affected (NOT normal for me!).
I constantly have the feeling of being trapped, and am beginning to wonder if I'm going a little bit insane.
It does feel good to be able to talk on here though - I already feel as if I'm amongst friends.
I will continue to have a little whinge if that's ok - it's so nice to talk to grown up people who can read and write in REAL language! 
Thank you all
Bobbi xx
