I think the lyrics and the video have two different meanings.
The lyrics are fairly ambiguous, so the actual meaning could and probably is different from person to person. Generally, though, the lyrics tell a story about someone who is hurt as the result of a past or pending failure. His "walls are so high" meaning that he lets no one in; he is withholding his feelings and distancing himself from those he cares about.
Eventually, he decides whatever mistake he made was the final straw. He's giving up the fantasy that he could ever be successful. He's facing reality.
He just wants to stop taking the failure personally. It hurts just to think about it - can't he just stop taking it in pain?
He's given his heart to a cause (most likely another person in a relationship). His heart was exposed, vulnerable to injury and pain - and it happened. Now, he has to move on from the fantasy of happiness.
The video, in my opinion, has a different twist to it.
LITERAL PLOT: The main character of the video is a teenage girl (Girl 1) who is hanging out with her friends (Girl 2, Boy 1, Boy 2). They sneak into a pool and have fun. Soon, it turns into a promiscuous night, as Girl 2 and Boy 2 start making out. Boy 2 begins fingering Girl 2. This encourages Boy 1 to make advances on Girl 1, but she feels uncomfortable and out of place. She's but an innocent girl likely in her pubescent years. When he leans in to kiss her, she panics and dives into the pool. She sees something moving around in her pants, so she panics and swims back to the surface. She sees Girl 2 and Boy 2 have transformed into extremely alien and terrifying creatures. Boy 2's hand has turned into a large tentacle that is inside Girl 2's entire abdomen. Girl 1 dives back into the pool to escape, finds a portal through the bottom of the pool, and finds herself in a terrible wasteland, where she collapses in defeat.
INTERPRETATION: The video is a metaphor for the loss of innocence. The anecdote of the girl being sexually confronted, her attempts at escape, her view of sexual activity as alien and terrifying, and her eventual defeat are all representative of the internal conflict that every person goes through when he or she loses innocence. The cause of this can be death of a loved one, bullying, or anything traumatic. The loss of innocence is what transforms a child into an adult.
