Need to vent and need some advice...

Amanda • Pregnant with my 3rd and mommy to an amazing 10 year old girl and almost 3 year old boy❤️
For the past few weeks, I've been feeling incredibly down. My anxiety is up because I feel like nothing is getting done and when I get home from work, I basically clean up after everyone and go to bed. I'm exhausted all of the time, and I just want to cry. Then yesterday, I was leaving for work at 5:40 AM. I pulled out of my driveway, to find my cat laying dead in the road. I am devastated. He had been hit by a car. I picked him up, and moved him to the side and called my SO because I was crying so hard. Since then, I haven't been able to stop crying. He was my 1st rescue baby. The only reason he was outside was because he had gotten out, and wanted to hunt. We live on a farm. He never went near the road, so finding him there was difficult. Anyways, I haven't told my daughter and I don't know how. Every time she brings him up, I change the subject. This morning, she was going to feed him and our dogs and says "oh no mommy, were out of cat food! How will we feed Rocky?" I told her not to worry about it right now but I know when dinner time comes for them she'll asks again and where he is. I just don't know how to tell her because I'll cry and she'll cry....what would you ladies say or do?  I'm just so heartbroken over this. I know it sounds silly because to most he was just a cat, but he was part of our family even before my SO and I got together. My heart just hurts, and I know hormones don't help...
