Well I had a period for about a year where I was in the same situation as you but my diet got my symptoms under control by about 50% for the past 2 years. When I added the salt treatment about 4 months ago it got my symptoms under control by about 90%. So I've had it completely under control for the past 4 months.
I know how hard it is my friend but you will get better! I thought I would be depressed my whole life but I'm completely back to normal now!
Please give this treatment a try and see how your skin looks after a month, I really hope it works for you. If it doesn't then have a look for another one and never stop looking because there is a treatment out there that will help you.
And in reply to the question about your son, I'm not to sure but I know that my mum/dad/brother/uncles/aunts don't have it so I wouldn't worry.
