I think it’s normal that if life hasn’t gone to plan that when we (usually wrongly) believe our ‘youth’ is over that it can feel quite crushing, I have certainly been there but what I’d say from my own experience is that if you are suffering from depression then that voice in your head can be very loud and very convincing but it’s normally wrong. You’re totally right about 15/16 year olds and asking them to choose their future, I’d say it’s pretty rare that someone of that age knows for sure where they want to end up, but there seems to be a social standard to commit yourself to a life when you’re not really ready. On the drink, I’ve always believed the drink exacerbates your current mood. If you’re feeling shit then it will make it 10 times worse to get pissed. Again, personal experience but under the right circumstances I can have a drink and be fine the next day, but if i use it to numb the pain or to avoid issues then I will be in for an incredibly difficult day afterwards.
