Hi Benjamin, and welcome to the forum.
As already stated, Goldfish and Rosy Reds are not good food for your Garter. I also think it would be wise if you could try to overcome your aversion to feeding frozen/thawed pinky mice. Their use, at least as part of your snakes' diet, will help to prevent problems both with health and availability of food further down the line.
