The single girl in the room

I am the single girl in the room. Everyone around me is either married or getting married. My sister got married six years ago to a wonderful and sometimes dorky guy and now they have two beautiful and wonderful children. My mom also remarried six years ago to a wonderful and dorky guy who drives her crazy at times but you can tell they love each other a lot. One of my best friends also got married six years ago to her high school sweetheart whom she loves to no end and have 3 children together, one of which sadly only lived an hour but the other two are beautiful and healthy. And now my baby brother is married before me to a wonderful girl who he loves with all of his heart and she loves him with her whole heart. They know each other like the back of their hands. My friends are all married, married with children or are getting married. I got an invite from another friend who is getting married who is younger than me. Don't get me wrong I am happy for all my friends and family for finding their happiness but I feel like I am a third wheel anymore and I don't want to. I want to know when I will find that perfect person for me? Where is my happy ending? Where is my frog to kiss to turn into my prince, my white knight? WHEN IS IT MY TURN???!!!
