Perhaps love isn't exactly the right word.....priority would, perhaps, be better.
Love is action. It is the determination to do good for the beloved. So, when someone whose only priority is to get high or drunk treats their "loved ones" in a way that is not for their good, then love is definitely not the correct word. And yes, people who have addiction problems do not "love" themselves either because they are not doing themselves any good and are even lying to themselves.
What I hope you will do is continue to read the stories on the F&F forums and keep an open mind. I also hope you understand that when we need to vent, we need to vent. Just like when someone struggling with addiction needs to vent. You have received many really wonderful responses here, and we do appreciate hearing from those who struggle with addiction because it does help us to understand. It's why I read the threads in the A and SA forums here.
Take good care,
