Dear On the Low Down~
Welcome here to the Support Forum, a good place to come to. While it might have been difficult to write down these facts about yourself I'm sure you will benefit. There are so many of us here who have been though something somewhat similar and wish to help. To answer your question, yes, if you are like me, you can recover to the point you can handle these occasions.
I have an anxiety conditon (plus other matters) and have had it for a long time. Like you I started off with panic attacks, feeling much the same a you did, unable to communicate, frightened, seemingly powerless and an object for others to gaze at.
I also had physical symptoms, from trembling, quite violent at times, to stomach problems to ... well a long list would serve no purpose. I still take medications both to treat specific symptoms, and also for the anxiety itself. I've undergone various therapies but have now reached the stage where my meds suit me, my therapy does good and I'm able to lead a very normal and enjoyable life, giving and receiving support and love, and working and gaining satisfaction from it.
If you are on meds then you already have medical support, that was crucial to me, however there is a fair bit one can do for oneself to meet difficult circumstances and hasten the recovery process.
A supportive person in your life too greatly helps.
As part of a very large amout of information on this web-site about anxiety are some ideas you might follow -if you are not already
In addition the methods others here have used
This thread is LONG, but I've gleaned a lot from it.
When faced with an event I'm sure will cause me heightened stress (like an interview) there are a couple of things I try to do, the first is preparation so thorough you can talk almost automatically, and the second is the use of a free smartphone app
Which - after practice - I found excellent, breaking my chain of thoughts away from whatever I was anxious about and leaving me in a calmer state.
I'm sure you are thinking this is all very well however it is the unexpected that can blind-side you. The good news is that as you improve your reactions do become less anyway, that is what recovery is all about. Not instant but there.
Would you like to come back and discuss this more?
