What do you think I should do? My parents keep alcohol in the pantry which is not hard for me to access, and of course they wonder where all their alcohol goes... they don't suspect it's me, they would never go to think I'd do a thing like that. They think it's my older brother drinking but I know for certain it's not him, I don't want him blamed for something I did! How should I break it to them without hurting their feelings? Or should I keep it to myself?

Please tell them, not only so your brother doesn't get into trouble, but also to get yourself some serious help. You are on a very dark road that will lead to tragedy if you don't tell your parents and get into a 12-step program.

I don't think you will "hurt their feelings."

All right, if you insist... I will have to swallow some confidence before I do so. :-) I will tell them soon I promise..

No, you don't want to swallow any confidence. You want to bite it off and chew on it so it will make you strong.
