Hilarious Instagram user captures the depressing life of a third wheeler

Ah, love. There's nothing like having that special someone who you adore so much that you can't help but cosy up to them.

But when you don't have that special someone, witnessing those public displays of affection can transcend disgust and sadness until you are left with nothing but cold joylessness.

And one Instagram user has hilariously captured that soulless feeling with a series of posts.

The unnamed user behind "Third Wheel Extravaganza" stares blankly at the camera while friends of hers hug, kiss and generally canoodle in the background.

"Thankful for third wheeling," she captions one post.

Her Instagram page has become a viral sensation in recent days, with the user celebrating her 1000th follower with a collage of her dour expressions.
