Only trying to battle them with facts and knowledge but the anxiety lets the emotion take over and make me doubt the facts.
Yes that's it - that's exactly how it works, the emotions over power the facts, make us doubt the facts and this fills us with fear. When this happens our fight and flight mechanism is activated and the logical part of our brain is sort of by-passed, the logical part of our brain is only really available 100% when we are calm.
So this is some more knowledge that you have to apply to the situation and when you apply it you will hopefully realise that because you can't think reasonably/rationally when you are anxious, because when you are anxious the logical side of your brain isn't working properly, there is no point trying to "think" your way out of the situation as "thinking" now will only make things worse and your "thinking" will not be 100% logical/rational it will be coloured with the over powering desire to "fight" or "escape" the situation and that will just baffle you because you don't know what it is you want to "fight" or "escape" from, because there is nothing there apart from .............
The truth is it's your thoughts that are trying to "escape" - because it is them that is causing the anxiety, it is THEM that you want to "fight" or "flee" from and you just don't REALISE it and so are baffled instead. Because you are baffled and are desperately trying to SOLVE this problem (to "escape" this problem) you question these "facts" to see if they are what is baffling you.
Well its not - your fight or flight mechanism has been activated and you want to run from want activated it - now the ONLY way to "escape" (flight) your thoughts is to calm down, if you calm down you'll be fine - but you don't recognise that as the problem and so because you are unaware of the REAL solution you are causing more anxiety and PANICKING (and quite understandably), out of sheer bewilderment.
Hope it helped
