If you don't want to drink, don't. You make decisions based on good reasons now. If you are mindful of feeling sad, you can ask yourself if drinking will make you less sad, or more sad. If you are feeling bored, will you become more or less bored?
Take it apart and break it down. What are you feeling? Sit and just be with these thoughts - nothing bad will happen. You can give yourself a shot in the arm by just allowing yourself to be as you are right now.
You are kind, and smart, and good and brave, all sorts of good things. You can do what you need to do, and be who you is. Something something. Anyway, you can do this if you simply believe in yourself.
