I hit a small squirrel and feel so horrible!

Am

This morning when leaving my neighborhood a small squirrel darted out into street and I slowed down while it went back and fourth in the middle of the road in front of me and thought it was between my tires but when I looked in my rear view mirror I saw it half dead moving on the road! I feel so horrible and keep replaying that image in my head and it makes me cry:-(( I drive back within 2 min and it was for sure dead but I feel so bad it suffered:-((((
