Drinking Problem?

Hmm.
Well.
Before I begin, I'm 14.
My best friend Jess, thinks I have a drinking problem. Which I do not. Just because I drink any form of alcohol every night. No different to a glass of wine at dinner.
Here's a conversation we had over the phone when I was drinking wine last night:

Her: You have a drinking problem.
Me: Haha, I don't.
Her: Not yet anyway.

I don't know. Last night I drunk about 5 glasses of red, fortified (That's wine with alcohol added into it) wine. And I had a bit of a hangover for school.
I drink when I'm happy. I drink kinda excessively when I'm sad. That's just it.

It actually scares me a bit.
I try to drink to the point that I'm happy. It's been said that "Shahle Drunk, there's 3 sides, 3 S's, Silly, Slutty, Sad." When I'm at the sad point, bad things happen, I try kill myself, bawl and scream, not good.
Apparently, I'm good as a happy drunk. And I develop a British accent (WTF?!)
I drink anything and everything, except for bourbon (EW!). I love Absinthe, my favourite.

Gah, I'm sorry about the rant. Anyway, this is just what stresses me, so I'm venting. =]
