I'm 18 with a bullet, got my finger on the trigger... I'm gonna pull it

LAst night I went out for Kat's birthday and it was really nice, we went for a meal and then to the pubs, her friends where also lovely. Tonight I'm having another party because my mum has gone away...again. We don't celebrate Easter so it's fine. I currently have a lot of college work to do and I really need a hair cut. You know when you just have a feeling in your stomach that something wrong is going to go wrong? I have that about tonight, I have a feeling there's going to be some sort of fall out/argument or something like that and I have no idea why. Fingers crossed that I'm wrong!
