I accidentally killed our kitten

I killed a kitten. A kitten na sobrang close sa aso namin. The kitten is still like a months old. Ginising ako ng mama para iatras yung sasakyan, di ko napansin na yung kitten nasa may wheel, so pag atras ko. Nangyari na. Kanina pa ako iyak ng iyak, and di ko alam paano sasabihin sa anak ko with Autism what happened to me. Nagtataka sya kanina pa ako umiiyak. He only know because of the cat, so ngayon gusto nya na ipa cage muna mga pusa namin, sabi ko naman wala silang kasalanan, and never nila yun naging kasalanan bakit ako umiyak — I can’t put what the right words to say to him na I accidentally killed our kitten. I’m blaming myself, and keep on replaying that split seconds before the incident happened. I don’t know if i’ll get over this mourn and grief.
