Why Do I Feel Like Shit All The Time?? :(

I don't know.. it just seems that all this week I've been feeling completely shit about myself, for various but not valid reasons. Hmm... at this point in time I can't even remember what the reasons are, and that's making me feel even more shit! I'm constantly feeling sorry for myself, even though I know others around me have MUCH bigger problems. I guess this just comes with being a teenager.. and it sucks sooooooooooo much. Being a teenager is different for everyone, some people find it more easier than others and people, like me, HATE it. It's such a confusing stage in a person's life, they're not a child but they're still not yet an adult. I don't even know why I'm feeling sorry for myself.. I guess, it's not exactly that I'm moaning "Oh, my life is SO shit, everything's going wrong for me" cos it's not, you know? I guess I'm just generally upset, I'm very emotional at the moment lol x Oh, it'll pass, it has to, cos it's nothing really. Just sometimes I'm scared to talk to friends in case I say something I shouldn't, cos when I'm in a pissy mood I usually say stuff I shouldn't, that I'll regret later. I am seriously confused now, as I write I'm just confusing myself even more. Am I upset? Am I angry? Am I feeling sorry for myself? Or am I just in a general everyday bad mood, but this time it's lasting longer? I have NO fucking idea, but I'm gonna stop writing now and update this later, when I'm thinking straight. God, I don't even want to read over this post.. It's probably just really messed up lol, toodles ;) xx
