Been drunk for the last 5 hours since 2 pm, it's currently 7 pm PST

I'm not claiming to be an alcoholic, but due to a girl I really like, and feeling like I haven't received enough attention from her, I fell into despair and drank. I'm 23, I'm too old to be dealing with shit like this, I'm an adult for crying out loud. I'm halfway through a 750 ML of Watermelon smirnoff flavored vodka. Is there anyone who can give me some comfort, or anyone out there who had similar drunk experiences?
