I am so sorry for the pain you are going through...
my son "found it" and "lost it" more than once and each time was so painful.....
I tried not to get sucked back into the chaos but I usually did and then had to crawl out of a hole myself
please try to hold onto your recovery tools...
he did it once and can do it again but it is all up to him
ugh...I've had moments when I've looked at my son and actually thought "too bad I'm not the addict instead of him...I'd be able to beat this"....guess that shows that i just don't get it at times...LOL
please know I am praying for you and your son...
