You are not alone!
Most of us here lost ourselves in trying to rescue an alcoholic from their own consequences.
I had to accept the three C's of addiction:
I did not Cause it
I can not Control it
I will not Cure it
Can you give yourself a goal today of No Contact with AF for 24 hours? No Contact means you are taking a time out from all forms of communication with the addicted person so that you can begin to focus on your own thoughts and needs. No phone calls, no e-mails or texts (delete them or have a friend read them), no facebook or other social networks, eliminate all forms of contact. In the event of an actual emergency, your AF can call 911 or his parents.
