Thank you all for the responses. The statement regarding the obsessive checking of BP is something I can certainly relate to and this I believe is part of my problem. Since I had the first noticable spike incident I have been very fearful and frightened of recurring spikes due to my experience and hence this I think is a major causal factor in terms of creating my anxiety. It becomes a very vicious circle. I firmly believe the anxiety establishes itself firstly, in my case, and consequently this triggers the blood pressure increase/spike. Question is how to control and rid my mind of this and ease the tensions/anxiety/panic and so forth.
I am not one to usually participate in such forums, however I have found this genuinely useful as I am able to place into words what I feel.
I never realised and appreciated anxiety/panic attacks could be this bad. It is worse, in my view, than physical pain. At least with physical pain you know what to expect and can more often than not ease the pain. It is not pain I feel, it is a feeling or sensation that is hard to describe and is worse than pain, it is that feeling of doom, uncertainty and loss of control. Very bad.
Anyway I must repair myself.
