Good for you, Love! I knew you could do it. You showed a self-awareness, so I knew it was possible to get through it.
You are intelligent. Probably quite creative too, whether you know it yet or not. You'd think these strengths would always easily lead you to make good and healthy choices. But sometimes, intelligent creative types hace a tendency to ponder so much, to see both sides of the coin, to see and observe and wonder about so many things that it can actually confuse you as to which wsy to go.
It is GOOD that you want to find creative outlets - you will then have tools to express yourself, to calm the different directions you may feel pulled in.
I'm not putting this as well as I'd like...just woke up. But I hope you catch my drift.
It's clear you are gifted. Life will have you.in many situations and circumstances where you will have to.choose wisely for your own future and present good.
You have what it takes - you just proved it to yourself. Remember that.
As for smoking....I've been trying to quit myself. Perhaps nicorette lozenges could help, ask your parents. They deliver nicotine, so you can break the actual hand-to-mouth habit more easily, and then work on using less lozenges.
Good luck to you my Friend

I sincerely hope you're as PROUD of yourself as we all are.
Peace.
