Geri's son Greg struggled with drug addiction for half his life. At 15, he began smoking marijuana, but that turned quickly to heroin and becoming hooked on fentanyl. He overdosed multiple times and thankfully survived, but it was never enough to scare him from picking back up again.
Institutions, jails, rehabs... Greg was at them all, and they all worked at the time, but every time he got out, something triggered him and he went right back to using. It is a vicious cycle and one he could not stop.
Geri has done all she could possibly do, but if the addict does not want to stop, there's only so much you can do. It's choices Greg made that got him to where he is now, which is still in the throes of addiction. But Geri will never give up on her son. She will keep trying and won't ever lose hope.
