for example.

if I am bending the G-string, when I release it or let go of the string, I can hear the D & A strings rattle a little bit through my amp.

I felt like throwing my guitar against the wall, I thought I knew how to bend.

how do I fix this?
You just need more practice. Mute out the other strings while bending.

make sure your bending properlyas well, use at least 2 (id suggest 3) fingers to bend, it give you more control rather than using just the index finger.

instead of just letting go ease the string back down or basically unbend the string with your finger

I'd suggest you try to palm mute those strings you are not bending(apart from the high B and E). That mutes them(doh) and with some practise(which also helps) you will automaticly mute the other strings.
Try muting your lower strings with the edge of your thumb -- that way you can quickly release the g-string without hearing the others rattle. It takes some practice, but this will improve your technique for any other songs you play, especially with high gain.
