It's probably difficult for you to get a balanced view of this, but some additional things to consider:
Nature is a harsh environment and animals die in horrible ways all of the time, most of the time we condone this happening by what we eat and only fail to face our complicity in this by allowing ourselves to be ignorant of the methods used.
The fact that you feel bad for this shows that it's not in your nature to want to harm; imagine instead that what was hurting these animals is a monkey on your back that you're seeking to conquer; a separate beast forcing your hand.
Most of us live in a society which raises animals to the nature of "people," view their behaviour in human terms and conveniently ignore the true nature of their behaviour. The loyal dog who is your lifelong friend would eat your rotting corpse if it got hungry enough.
This inappropriate way of viewing animals is in itself enough to raise the appropriate level of guilt over your actions to that of a murderer which is vastly over-stepping the threshold of it's true nature.

This reminded me of an excellent example quoted in the bible where Jesus made a herd of pigs jump over a cliff to cleanse a demon-possessed man of his ailment. He seemed to value one person's mental health as more value than a herd of animals, leading them to a frightening and tragic end.
And let's not forget Noah's wiping out every living animal on earth by drowning, save two of each kind, as a punishment for mankind's behaviour.
In summary, yes...work to overcome your addiction as it will do nothing but screw up your head further if it continues, but have a balanced view of just how "bad" a person this has made you.
