I've been feeling really lonely and somewhat depressed lately. I was out with my friends on Friday as usual, but for some reason, I suddenly felt like the odd one out. Everyone had a loved one on their arm and for the first time in a really long time, I was conscious of being the third wheel. I didn't see a group of 9 people, I saw 4 couples and me.

I think matters just got worse when I went to see The Time Traveler's Wife. Anyone who knows me knows that it's my favorite book of all time, but only perhaps my closest friends know that I gave that book to MCAT Girl once for Christmas. Seeing the movie reminded me of her, and as I sat there in the theater watching this love story play out in front of my eyes, I felt that pang of loneliness again. I never stopped wondering what happened to her and how her life has changed.

My friend just proposed to his girlfriend tonight, and though I couldn't be happier for the two of them, it just reminds me of how far away I really am from completing all that I long for in life. In fact, every one of my friends now have that special someone in their lives. I can't help but wonder how it will be in the future when everyone has gone their separate ways, leading their separate lives.

On those days when I'm holding my friend's baby daughter, my heart just aches for a child of my own. For all my successes in life, the one true thing that really matters still seems to elude me so.
