Lyric discussion by upthorn 

This is just my interpretation, and it's a fairly superficial reading, so it could be wrong, but...

He's depressed, and trying to find a niche in life where people won't treat him badly. More specifically he's trying to find a place with someone who loves him, hence "I won't be there alone".

He found it before, but didn't recognize it, and tried to kill himself. (Cause I bled. And you watched.) And when he tried to explain, he found out the person who loves him is too scared to be close to him now. But he knows that person will come back eventually, "because of the love for me."

I can probably make this more sensible in the morning.
