Welcome! You are doing the best thing by going to Nar-Anon. Get in as many meetings as you can (Al-Anon works too).
Your daughter only recently became an adult. She is often making poor choices. It is hard for any parent to just stand by while that happens. However, she is a person in her own right and, with this disease (heroin especially), one must set tough boundaries. Those boundaries will protect you and give her an unenabled chance to do the inside job she needs to do to escape the claws of this disease. For many parents, that entailed putting their A out of the home.
These difficult times, decisions and follow-throughs have mostly been possible only because of the cameraderie of Experience, Strength and Hope found here and in those rooms.
I bid you Serenity.
