Dealing with grief

In the last 2 years, I have buried 3 special family members, faced a surgery that could have killed my spouse, faced my spouse going off his psych meds, that could have destroyed our marriage. Today, I got the news, that yet another treasured family member, has lymphoma. I could lose her soon too. I will add this is my pet cat. She has helped me deal with so much of the other crap that’s happened in my life. It’s tearing me apart to hear I am going to lose her soon too. My pets are what help me get through tough situations. I don’t know how to deal with all of this death. How does one get past losing so much? I am struggling hard now to keep my faith. I never doubted God before, but now I am having trouble.handling all that has happened.
