Hi Needsleep
Addiction loves nothing more than to be kept a secret. Not talking about this stuff just enables it to go on and on unchecked.
You should be able to talk to friends at least, or a professional and be able to share where you are at and take advice from trusted people. You need this for you first and foremost as it is clearly affecting you. There is nothing to be ashamed of here – it isn’t your shame and you mustn’t carry it.
It sounds like it’s at a serious stage now and you have to ask yourself if something bad happens, could you carry the weight of not talking to his family and letting them know? It’s a big question.
Reading what you wrote about your husband, and having personally been where he is right now taking that exact same combination I can tell you this is going to get worse and worse.
Benzo and opiate mixing is dangerous and cam be lethal, a Google search will explain why. Mixed together they give a sense of euphoria and relaxation which feels amazing to the user, from the outside looking in as you are they just look completely levelled. Also, quitting won’t be easy as he’s been doing it for a long while and is likely to have a double whammy of withdrawals at the same time.
My guess is that his choice of drugs and also the cutting suggests he can’t manage his emotions at all without using.
Is he open to getting some help?
Can you get some support or help?
