When I Bend My High E string i get this weird sound, not through the amp just on the guitar you hear what i can only describe as wood cracking. But i don't think the wood is cracking, that's what it sounds like. D'You Know What I Mean?

it's probably getting caught in the nut, rub some chapstick under and on top of the string. that's what happened with my guitar anyway, the chapstick fixed it

Didn't know about the chapstick but graphite shavings (from a pencil) work perfectly.
I pick up my guitar and play

yeah its pretty normal, the string is probably close to breaking, you could just replace it.
