@ Comparables- As pessimistic as what you wrote sounds, it is entirely true. I have had a few very close friends die from drug addiction, and I have lost family members to addiction. My fiancée’s sister recently lost her child to the state because of her addiction. My fiancée used to care for her child on a regular basis, and it was hard for her to deal with when she found out.
Honestly, my fiancée will likely lose her sister to her unshakeable addiction in the next few years. She has been committed, arrested, and bounced off the bottom a few times, but she doesn't want to change. All my fiancée can do is hope that this doesn't happen. All I can do is brace for when it does, and promise to be there for my fiancée.
