You’re not actually fooling anyone; at some level, conscious or subconscious, the people around you are aware you’re addicted. Sometimes it doesn’t come up just because it’s been happening so long that they (and you) just think it’s your standard behaviour. Still though, they are aware you are an addict. (That’s why this happens: You might be an alcoholic if - #395 by Runningaway - and that’s just the people who actually talk to you about it.) You’re not alone; many of us at one point or another lived with the illusion that we were somehow getting away with something, all while we kept ourselves numb and underperforming due to our addiction.
So, so many of us here can say exactly the same thing - you’re definitely not alone.
You need to do something new. You need help. Have you tried joining a meeting? www.AA.org or www.NA.org; there are others too; you’re never far from a meeting. There are also all kinds of meetings online (including some 24-hour ones: search “marathon NA meeting”, for example, and you’ll find some).
It’s time for a change. What’s your new thing you’re gonna do? Then just go do it. A lot of this only takes a couple minutes to do. Go for it!
