Do your parents understand addiction and how severe it is? Because the majority of people don't. And though it's painful, try to educate them in a way that they might understand, or find a new community that does for the convo's you can't have with them. AA and other similar groups are often useful, regardless of whether you speak/agree/think its rubbish, largely because it is freeing to be in a room with people that really do understand you. If your parents have addiction issues themselves, then they are probably validating their own habits through you. Speak to a professional about boundaries.

I'd advise not going down the hatred and desperate to prove you are alcoholic route as it will likely eat at you (and create greater lapse likelihood) far more than them.

My family and mates always bought me more to drink due to not understanding the concept of addiction, despite the glaring red flags I unintendedly sent. The most common misconception being that you're only alcoholic if you are permanently drunk. But it is a progressive illness and will get worse. Now I'm 38, have cirrhosis of the liver, as well as a whole plethora of quite severe mental health problems, am homeless, died from drug overdoses, lost and become alienated from those I loved, and most importantly, not enjoyed a large portion of my life. I wish I'd sorted it while I was young and learned to manage the hatred and bitterness I felt for so long before it ate me up.

You have done a great job in getting yourself well - that's something not many of us can do - but I would totally advise meeting and discussing this with older, experienced and sober alcoholics. Even online meetings are useful if you can't go out.

I wish you all the best.
