Hey Chu
First of all, the situation you’re in will be extremely stressful. Addiction is indeed an illness. I can attest to that. Whether it’s from pills, powders or liquids, it’s still an illness of the mind. You’re not alone. Many families throughout the country are going through the same thing.
Your father is your father, no matter what anyone says. He’s still your dad who you will love no matter what. That’s what makes it more painful. Your husband needs to be a little more thoughtful and understand the situation you’re in. Tell him: “Put yourself in my shoes, if it was your father”. Anyone can become an addict. It’s usually negative events or underlying mental health problems which lead us to escape reality. It can also become a routine addiction. Some people don’t even realize they’re doing it, because it just becomes a part of life.
What you need to maybe do is try to get your husband to support you in regards to your dad. If he’s on board it will make it much less stressful for you at home. Tell him how you feel, and that you’re seriously worried about your fathers’ health. Tell him you need his support so that you can attempt to get your father back on the straight and narrow.
It’s good that you’re on here instead of bottling it all up, which just makes it worse. I hope you find a solution so that your father gets the help he needs. You’re not alone.
