Hair Loss is not always temporary

I have some hair - just not enough to pass for normal.  The research papers I've been able to pull up say the side effect is dose dependent and not everybody gets it.  I know my cancer is high-risk and I had a heavy regime which is why I'm wondering if I might have been overdosed.  Somehow the knowledge that most people get through it and go on in life doing all the things that is talked about in the websites, the leaflets, the supports groups etc, makes me feel even more cheated that I don't even fit the 'breast cancer journey' profile if there's even such a thing.  I seem to be on a lonely and different journey that doesn't go anywhere.  A year after treatment finished I attended my daughter's wedding almost bald and looking horrible.  I could have worn a wig but she wanted me to be me.  I looked terrible - not me at all.  I have none of those wedding photos in the house.  They are of a stranger - the same stranger I see in the mirror every morning.  It's not me.  I am now one of the gullible people who are constantly searching for any solutions from quacks and sales people because the medical establishment cannot offer me any solutions.  I have now been 'treated'.
