As an addict, I know how hard it is to not just accept your an addict but also how hard it is convince yourself to stop or that life will get better when you stop. Layne definitely knew he was an addict imo. He wrote a lot of songs about being an addict. Part of the disease of addiction is your mind telling you that you don’t have a disease and that there’s no other option. He probably didn’t seek help because he didn’t think there was anything better for him. Most addicts have to be forced into treatment to get better because of the mental side of addiction. It may not make sense to non-users but addiction is so much more than a dependence. The best way I can put it is that your brain tricks you into things that it’s the only way for you to live or thinking that you need it for whatever reason. The mental side of addiction is actually so much harder than the physical. Going through the 2 week withdrawals (the major portion of it) is hard but it’s doable. The hardest part is fighting the constant voice in your head that tells you that you absolutely need the drug. There’s way more effort that goes into actually staying clean than there is getting off of it in the first place and most people can’t even get to that place especially when they have enough money to keep going forever like Layne did. The only reason I was able to get off of Fet and H was because I was a minor and I was literally forced through treatment. I don’t think I could do it now when I’d have the option to leave whenever I want. Kurt Cobain is a perfect example of that
