Pet death

I've been deeply sad this last week as my mom was in a terrible car accident where my 14 and 12 year old dogs died. My mom and her boyfriend will be okay and I am grateful for that but my dogs were flung from the suv and one died at the time and one died 4 days later because for some reason the vet didnt put her down and they didnt ask my family to see what they wanted. I can't stop thinking about it and Im so upset, it was one of those things as well where if my mom had been going just the absolute smallest bit slower she would be dead. I found out while on vacation 3000 miles away for my partners birthday, we were driving the 5 hours back to the hotel from a theme park and had been up for like 20 hours. I feel like im annoying my friends because I just keep being so sad thinking about my dogs dying scared and alone on the road while my mom watched, she couldnt get out of the car and had to be cut out. Or thinking about my mom dying.
