When did I grow up?

So, I just realized how old I am. I turned 19 on Friday. Sure, that's not old, but my friends are getting married! Rachel Swearingen is now Rachel Brewer. (Brewer? Seriously?) She got married in September. Valen's getting married in January. I missed her bridal shower yesterday because I didn't feel like going home. Rachel apparently thinks she's married. The other day she told me she had a husband and daughter now (which I guess means she's too busy to reply to my suicidal text messages). And Alicia and I have been dating for almost 7 months. That's a long time. I think I'm going to marry her. I'm terrified. I mean, I want to... but I'm terrified. This is all too soon. When did I grow up?
