Welcome, Missminime...
I have so much admiration and respect for someone your age stepping forward and trying to deal head-on with your problems. Congatulations!
55 sober days wonderful! I doubt I lasted five days without a drink when I was 20. In fact, until recently, I had not had 5 sober days in a row for over 25 years.
You will find a lot of wisdom, love, and support here. I can promise that nobody will judge you for your problems.
In my opinion, you have started dealing with your problems exactly the right way: staying sober first. I'm sure you know that it is impossible to think clearly while drinking.
Please feel free to open up and share yourself. You might be surprised at how many people here have similar experiences to your own.
Earl
