Suffering from sever depression, I understand your outlook on life very well. I sometimes wonder if the only reason I never started smoking as much as you do is because of limited availibility. But in the nights I spend sober, laying awake in bed thinking about the horrible state of existance, I am thankful for the few loyal friends I have. This isnt to say that I never doubt thier loyalty, but in the grand scheme of things, it is great to have them there. There will come times when you will, for multiple reasons, not be able to smoke. You just need to learn how to deal with life in those times. Plus, you really will cherish smoking so much more. TALK TO YOUR FRIEND.
On the second hand, get yourself into college and you'll make plenty of new ones with similar mind sets. Dont worry too much, im sure things will straighten themself out some way. Peace.
