Instant Menopause

I am triple negative and only have Chemo and Radiation as my methods for Cancer treatment.  I was just guessing about the Menopause, as Im not a doctor and havent talked about it because its only just starting to happen.  I found myself in a sticky situation and panicked, I was dropping my friend off for a bus, and there was no where to park and I had a bus trying to back into where I was.  At the same time friend removing suitcase and I felt trapped and panicked.  I didnt realise it was a matter of simply driving through a drive way, but it wasnt signed, and I yelled to myself "Now what am I going to do?"  I did take off and leave my friend behind, with her suitcase, by sent her a message when I got home, she totally understood.  The point is, I reacted totally differently and reacted frantically.  I kinda think its like a post traumatic response, and I will ask to speak to the Councillor linked to the General Hospital, when I go in for Radiation on the 22nd of May.  It was out of no-where, but I also notice I get picky, think too much, and tend to get a bit caught up in it all, out here isolated most of the time.  Im sure with time, I will readjust, but the smart thing to do would be to talk to the Councillor.  Thanks for the replies everyone.
