You're wasting money anyway, by buying it in the first place.... it takes you further and further from your goals in so many ways.

Plus, what are you going to do once you get caught? You will get caught eventually.

And if you have to do things that are embarassing to get ahold of alcohol, well, that's just another sign that you really shouldn't bother.

You really don't need to add addiction to your list of things that are pulling you down...

You're just running so many extra risks for yourself with this new habit. You're risking ending up in the hospital due to alcohol poisoning, you're risking losing the money that your parents provide you with, you're risking getting kicked out of your dorm, you're risking your life as you said you feel more suicidal when you're drunk, you're risking your grades (hard to get your work done when you're properly drunk, also can affect memory), and you're slowing down your path to freedom.

Dumping it out might be a great way to sorta slap yourself in the face and go "aauuugh I really am wasting my money". And it's sorta a great big F U to your brain! (Ok, that sounds odd... I tell my brain to F off on a regular basis... I like to view things as Me Vs My Brain... haha... it works for me)
