I have to agree from what you said, things could get worse if you don't gain control. Some people are just born with a 'craving mechanism'...sometimes (in my case) alcohol triggered it. Once I started I could not stop...& I hit a hard bottom. I came close to death a few times, and finally realized I HAD to stop...or possibly die. This is a good place to start. I also go to AA meetings. You would be surprised that there are others out there like you, you are not different to alone for that matter. I wish I would have stopped when I was your age. I went through a lot of pain over the years and now live sober.
