To be perfectly honest with you I would imagine it’s actually more draining for the family and friends of the addicts because the addict who is still using a substance will (in my experiences and opinion) feel almost refreshed once they have the drugs they want/need and okay I know it all starts again once they have used it all but the family and friends don’t get that feeling of the pressure being off. I really hope that makes some sense.
I’m glad to hear you’ve got yourself a lovely little flat and I hope you are going to be happy living there.
