Tyler Posey had a rough 2014. The Teen Wolf star's mom passed away in December, following a dramatic breakup with his fiancée and girlfriend of a decade, Seana Gorlick.

"This has been the hardest year of my life. I still really miss [Seana]. I can't believe I have an ex-fiancée," he told People.

It was even harder when his mom, Cyndi Posey, passed away. (She was his business manager growing up and homeschooled him.)

"[My mom] was my best friend. She was the glue that held our family together," he confessed.

Even though he's still tight with his dad, John Posey, and brother, Jesse Posey, the actor says, "I've lost my sense of family. Whenever I have too much downtime, I start to get sad."

This is absolutely heartbreaking.
