I was very similar to your daughter and drank extremely heavily- most weekends- from the age of around 14 to 16, and regularly to the point of severe vomiting and blacking out. I was otherwise a very well behaved and an academically high achieving child. I got into so many high risk situations, and was ‘rescued’ by complete strangers several times. I was sexually assaulted many times, and taken complete advantage of by numerous older men.
Getting to the bottom of what is driving her to behave in this way is absolutely the critical step, but it won’t be easy and may just not be possible.
My situation is different in that my parents didn’t really care what I was up to, and certainly didn’t punish me. The only reason I was able to get alcohol at all was because they either bought it for me, or gave me money for me to get it myself. We’re going back 23 odd years now so times were different to an extent, but I still find it baffling as they were otherwise very loving and supportive parents. I think they both drank in parks a lot as teenagers in the 70s and just thought it was typical teenage behaviour?!
It’s hard to know what, if anything, would have worked to address my drinking, but it was definitely driven in my case by depression, anxiety, and very poor self-esteem and confidence. I was very unpopular with my peers at my all girls’ school and I also had an eating disorder at that time and was extremely underweight. I was absolutely desperate for male attention (and got it very easily when drunk) and it was the only thing which validated me. Being drunk gave me confidence to interact with others in a way I perceived as being fun and outgoing in a way that I just couldn’t achieve when sober.
I think anything which would have boosted my self-worth, and which would have addressed the underlying anxiety and depression, may have helped. There is no way that being told about the health consequences of drinking would have done anything, nor would shaming me by- for example- taking photos of videos of me while I was in a state. I couldn’t have cared less about those things.
In my case, I’m afraid to say I only grew out of it because I moved onto taking different drugs when I went to college at 16 and made friends with a really decent group of peers, albeit ones who liked to party, and getting my first boyfriend who was lovely. This itself offered me validation, as did continuing to achieve very highly academically and growing in confidence in my learning. The drug taking had nothing to do with poor self-esteem etc, but simply because I was young and it was extremely fun. I had some extremely good times. Honestly though, I still think my taking a bit of MDMA at weekends was considerably safer than getting blackout drunk, and none of the drugs I took ever put me in anything like as risky a situation as getting blackout drunk.
I had largely grown out of all drug taking by the time I was 21 and finishing uni (where it had no impact on my attainment or ability to hold down a job) and though I had some heavy drinking times particularly in first year of uni, I was largely sensible. I rarely drink now in my 30s, don’t take drugs at all, and haven’t done for years.
