OK, I shouldn't be here replying, I said I wasn't going to........but.......
Chlobo, nobody doubts how hard things are, nobody underestimates the awfulness of having to push yourself through fear and panic, its horrible and tough and you are 'fighting' the panic constantly and just about scraping through each day in whorlwind of adrenaline. I'm glad you are getting out and about and taking better care of yourself though.
BUT - to my mind, these are still not the right things you are doing. Where is the reassurance ? Where is the background work on a list to carry with you ? Where is the evidence that you are truly trying CBT techniques ? Where is the realisation that you have control over this ? Where are any of the points on this thread put into practice ? (Apart from putting makeup on , which is a distraction and self care activity). I still think you are missing the point here, and I don't know how to get it across any clearer than has been done. You are struggling through the day, fighting (people with anxiety aren't weak and lacking courage, as they put up with a difficult daily life all the time and carry on) , but because the background work hasn't yet been started you are still in the phase of struggling and trying to 'get through' with a belief that there is actually something physically wrong with you that you aren't challenging. That is evidenced by the fact that you returned straight to your arm, A and E and scans at the end of the post. I should think thoughts of your arm didn't leave you at all during your trips out.
Claire Weekes talks in detail about floating through the panic, not seeing it as important and aiming on losing the fear of it.....I still think you are feeling the fear and trying to get through it.
Maybe Nora can help here, she's better with explanations.
