Listener question: the desire to hide away

I wanted to ask you about a lack of motivation for the conversation I have felt since dropping out of the STRESS course, I am doing the YOU course but feel I'm just going through the motions.  I still enjoy and always listen to the podcasts, it seems to be the courses that are affected. When I dropped out of the STRESS course I could see that it was because the lesson (16) hit a nerve.  I was having to face my biggest fear.  I can see that it was part of SELF preservation but I'm getting caught up with SELF preservation and physical preservation.  The fear is around 1, having a seizure or panic and 2, having it where I am not safe e.g. on my own or somewhere I could inflict harm to myself and yes even die. Point 2 is clearly a sensible thing to thing about but how does it fit in with point 1 they seem to be connected. Life is also throwing connected things at me, like,  an old friend has asked me if I wanted to meet, in an area I have felt anxious before and she thought it would be where I would be dropping of my daughter for work, so I have to say I don't do that anymore,  I cant meet her and have to say why, that I don't drive anymore and that all my instincts are saying in ignore the message!!   I know I'm withdrawing and most of these things can be worked around.  I embarrassed about my situation and worry that she think she will be meeting the old Karen not this version.  All Embarrassment, self consciousness, fear and helplessness.Really want to hide from this.
